The particle theory of matter can be used to explain how solids, liquids and gases are interchangeable as a result of increase or decrease in heat energy. When an object is heated the motion of the particles increases as the particles become more energetic. If it is cooled the motion of the particles decreases as they lose energy.

# data[].attributes.body
When you change one of the factors that affect rates of reaction it will increase or decrease the time taken for the reaction to occur. E.g When increase the concentration more particles are involved in the reaction which will cause more collisions between particles as there is less space for them to move.

if one of these factors are changed, the rate of reaction is also changed. Eg temperature, when the temperature is lowered, the rate of reaction is slowed. lower temperature slows the constant vibration of atoms, the bonds between molecules become stronger and less likely to alter. sometimes turning non solids into solids. these bonds prevent reactions from occurring as often.

Increasing concentration of the substrate will mean there are more particles to collide with increasing the overall rate at which particles are reacting producing a product.

# data[].attributes.body
Increasing the surface area of one or both of the reactants allows more of the reacting particles to collide with the now exposed particles, this means there are more particles exposed and ready to react at once increasing the rate of reaction.

# data[].attributes.body
For a reaction to take place between two chemicals, the particles involved must collide with enough energy and at the correct orientation. The particles must have enough energy to reach the activation energy and break the bonds between the atoms.

# data[].attributes.body
Increasing temperature of a reaction will increase kinetic energy within the particles increasing the chance of particles to collide at the correct orientation and with enough energy.

When you increase concentration there are more particles which will cause more collisions between particles as there is more change for them to collide.

# data[].attributes.body
If you add a catalyst, the required energy for there reaction to take place would be decreased, therefore the rate of reaction would increase.

For a chemical reaction to occur the two reactant particles need to collide with sufficent energy and correct orientation. If these two prerequisites are not met the reaction will not happen

# data[].attributes.body
When you increase the temperature the reaction rate increases. this is because the amount of kinetic energy in the particles increase resulting in more collisions and higher energy collisions.

# data[].attributes.body
collision theory states that for a reaction to occur, the particles must collide with enough kinetic energy and be in correct orientation

# data[].attributes.body
For a chemical reaction to occur collision theory must take place. Collision theory is when the particles collide at the correct orientation and with a sufficient amount of energy to overcome the activation energy and break the bonds within the particles.

# data[].attributes.body
The rates of a reaction can be measured by the rate at which a reactant is used up, or the rate at which a product is formed. Changing the temperature could increase or decrease the number of energy high collisions.

# data[].attributes.body
When you change any of the factors that effects the rate of reaction, e.g adding a catalyst, the overall rate of reaction will be effected. If I were to add a catalyst, the activation energy required for the reaction to take place would be decreased, therefore the rate of reaction would increase as more particles would qualify to be able to react due to the lower level of energy required

by increasing the surface area of a one of the reactants, the amount of reactants exposed increases, which causes more reactions.

Collision theory is when particles collide with each other, with the correct amount of energy and oriantation.

# data[].attributes.body
All matter is made up of very small particles that are constantly moving.

# data[].attributes.body
Particles move around more at higher temperatures, so more collisions are likely, and the collisions will have more energy.

# data[].attributes.body
Particle Theory states that all matter is made of particles. The amount of energy which is present between each particle will control the state that the matter is existing in. Lots of energy = gaseous. Little - no energy = solid. In between = Liquid.

# data[].attributes.body
collision theory states that particles react with each other through collisions that break bonds and release energy [exothermic reactions].

# data[].attributes.body
When you change on of the factors that affect rates of reaction it will either increase or decrease the reaction rate. For examole if you increase the amount of heat it will increase the rate of reaction

# data[].attributes.body
The more particles there are, the bigger the chance of collisions.

# data[].attributes.body
A catalyst is a substance that changes the rate of a chemical reaction by giving an alternative plane for particles to react on the correct orientation

# data[].attributes.body
for a chemical reaction to occur particles must collide with enough energy to surpass the activation energy and have the correct orientation

# data[].attributes.body
When you change something that affects the rate of reaction e.g temperature it will raise the reaction rate because the particles are moving faster

# data[].attributes.body
When you change one of the factors that affect rates of reaction, for example, Temperature. Once temperature is increased, there are more particles colliding, meaning an increase in rate reactions. Whereas, for decreasing the temperature it will be the opposite.

# data[].attributes.body
If one factor changes, the rate of reaction will also change. For example, an increase in temperature will cause the rate of reaction to increase.

# data[].attributes.body
An increase in concentration will increase the rate of reaction as there will be more particles to collide with; the frequency

# data[].attributes.body
Rates of reactions are measured by the rate at which the reactants are used up. When you change one of the factor, the rate at which the reactants are used up will either decrease. e.g. increasing the surface area of the reactants will increase the rate of reaction as more particles can collide at any point in time, vice versa.

# data[].attributes.body
Increasing the temperature in the reaction will cause the particles to move around more which causes more collisions within the reaction. Causing the reaction to occur faster.

# data[].attributes.body
The four factors that affect the rate of reaction are; Temperature, Concentration, Catalyst, and Surface area

# data[].attributes.body
If you increase the concentration the reactant particles become more crowded, which then creates a greater chance of the particles colliding.

# data[].attributes.body
when you alter the concentration of a chemical, more reactions happen due to more collisions happening at once. the higher the concentration, the more particles there are to react as well.

# data[].attributes.body
By decreasing the temperature of the reactants, the particles would be moving slower and would not have enough kinetic energy to break the bonds and cause a reaction

# data[].attributes.body
Temperature:
When the temperature of a chemical reaction increases, the particles will move faster and so have an increase of energy for reactions to occur. Because the heat will make the particles increase in speed, the frequency of collisions will also increase, increasing the rate of reaction. Whereas if you decrease the temperature of a chemical reaction will cause the particles to move slower and have less energy, making it less likely to have sufficient energy for a chemical reaction to occur. This will also decrease the frequency of collisions in the chemical reaction, decreasing the rate of reaction.

# data[].attributes.body
Increasing the temperature of the reaction will also increase the reaction rate as this increases the amount of energy within the particles, therefore, allowing more activation energy for a collision.

# data[].attributes.body
(For Heat)
Temperature is defined as the average kinetic energy that a group of particles has. Increasing the temperature at which the reaction occurs will increase the rate of reaction in two ways: Not only will particles move faster, increasing the number of collisions and therefore successful reactions, but also each particle collision will be more likely to overcome the activation energy required for the reaction to be successful.

# data[].attributes.body
Increasing the concentration increases the amount of particles to collide with each other

# data[].attributes.body
Adding a catalyst to the reactants increases the rate at which they are reacting by lowering the activation energy required for the bonds to break allowing the now free particles to react at a faster rate than without a catalyst present.

# data[].attributes.body
Collision theory is the process of particles successfully colliding with other particles with sufficient energy and the correct orientation.

# data[].attributes.body
The particle theory states that all matter consists of very small particles that are constantly moving or are in a state of motion. The amount in which these particles move is determined by the amount of energy each particle has and its relationship to other particles.

# data[].attributes.body
particle theory states that all matter in the observable universe is made up of particles. the theory also states that the states of matter are caused by the energy between these particles. (higher energy for gasses, lower energy for solids.

# data[].attributes.body
Increasing the surface area then more particles are exposed to the other reactant, creating more surface area is done by cutting or grinding the substance.

# data[].attributes.body
Increasing the surface area of each particle will make the reaction happen faster because there will be more collisions as there will be more particles to hit. This is done by spitting clumped particles so they are all spread out.

# data[].attributes.body
Increasing the surface area allows allows more reactions to take place, hence, a faster reaction rate, because the particle will be more exposed to oncoming collisions

# data[].attributes.body
Increasing the surface area increases the area of which particles can collide with each other resulting in a higher rate of reaction

# data[].attributes.body
by increasing the number of particles (concentration) there are more reactants available for the particles to react with

# data[].attributes.body
Increasing the concentration will mean that there are more particles/reactants in the reaction so there is an increased chance that particles will collide with another to undergo a chemical reaction. As the chance of collisions increases, the rate of reaction also increases.

# data[].attributes.body
Increasing the concentration will increase the amount of particles present in the reaction therefore increasing the amount of successful collisions.

# data[].attributes.body
Increasing the catalyst will lower the activation energy, with catalyst more collision in a reaction so the rate of reaction increases.

# data[].attributes.body
Concentration - When concentration is increased

# data[].attributes.body
by adding a catalyst to a reaction, the amount of energy required to break the bonds is reduced, which increases the amount of reactions taking place.

# data[].attributes.body
Adding a catalyst

# data[].attributes.body
the addition of a catalyst increases the rate of reaction, though it undergoes no changes itself.

# data[].attributes.body
OrderThe order of the reaction controls how the reactant concentration (or pressure) affects reaction rate.

# data[].attributes.body
When you change a factor within the reaction that affects the reaction rates it will cause the reaction to occur faster or slower. An example of this is temperature. Increasing the temperature in a reaction will cause there to be increased kinetic energy within particles so they will move around faster which will increase the rate of reaction because the particles will be colliding more at the right orientation and with enough energy. And if you decrease the temperature in a reaction it will cause the particles to have less kinetic energy so they will move around slower so the collisions within the particles will have less energy as they are moving with less energy.

# data[].attributes.body
The collision theory is the theory that particles need to collide with sufficient kinetic energy and at the correct orientation to overcome the activation energy and undergo a chemical reaction. Increasing the temperature of the reactants increases the kinetic energy in these particles and as these particles need to collide with sufficient kinetic energy to react together, increasing the temperature means that these particles will collide at higher speeds and have a much greater chance of overcoming the activation energy, reacting, and increasing the reaction rate.
