1: Outline the collision theory:

According to the collision theory, in a chemical reaction there must be some guidelines that must be met in order for a chemical reaction time occur. The first one is 2 particles must collide with each other, the second is they must be in the correct orientation and their reactive parts must meet, the third is that the reactants must collide with sufficient kinetic energy.

2: Describe + Explain the factors that affect reaction rate:

Temperature:
When you increase the temperature the reaction rate will also increase because it increase the amount of collisions in between 2 particles therefore more particles can react.

Surface area:
When increasing the surface area the rate of reaction will also increase. You increase the surface area by breaking down the substance into smaller pieces, this mean the particles are exposed to other reactants

Surface area is an important factor that can have a significant effect on the rate of reaction.

The explaination of this is when a reaction is going to happen between a solid and a liquid. The larger, the surface area the solid has, the more likely it is that particles will collide.

The Collision Theory;
- The two particles must collide with each other.
- They must collide in the correct orientation, so that the reactive parts of each particle will come into contact with each other.
- The reactants must collide with sufficient kinetic energy to bring about the reflection.

Factors that affect reaction rate:
-Surface area
This is exposing the chemical to other matters like water to create the reaction faster
-temperature
If you increase the temperature the particles will gain energy and this will increase the reaction rate

Temperature is a factor can that effect the rate of reaction significantly.

An example would be if you take 2 same chemicals and add them to a water, depending on the temperature, the reaction will either take more time or less time.

Mariam,nora,william
what is it :

it is a  theory used to _predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together orcollide with one another.

The collision theory requires 2 particles to collide with each other while in the correct orientation and the particles must have sufficient kinetic energy.

- particles must have sufficient energy
- The particles must be in the proper orientation
- There must be successful contact made in order of the collision theory to function

What is the collision theory? (Rohaan, Anas, Akansh, Abdulla)

2018-01-10 07:49:48 UTC

it explains the gas-phase chemical reaction taking place between molecules.
It consists of 3 parts:
1) All molecules are traveling through space in a straight line.
2) All molecules are rigid

Both particles must me facing each other correctly and should be in a position to collide.
