I hypothesize that changing the surface area of Fe the reaction will occur much faster

# data[].attributes.body
I believe that, if the surface area is larger, then the reaction rate will increase (the reaction will be faster) as there are less layers for the other reactant to go through.

# data[].attributes.body
I thik that an increase in surface area will cause an increase in the rate of reaction

# data[].attributes.body
I believe that with an increase in the surface area of the Fe, the rate of reaction will be faster. This is because when the surface area of the Iron increases, there is more spots on the iron that is exposed to the other reactant giving the other reactant more area to collide with the iron making the reaction go faster.

# data[].attributes.body
more surface area - faster reaction
i think this because more of the iron will be exposed to the acid, causing it to react. if more Fe molecules are reacting to the acid, it will dissolve faster.

# data[].attributes.headline
I believe that it does affect the rate of reaction. It speeds it up as there is more contact between the atoms of Fe and the molecules of the solution.

I think that the larger the surface area the quicker the reaction will be. Increasing the surface area of iron would mean that there is a greater chance for collisions, which would speed up the overall reaction.

i hypothesize that the temperature of the reactants would speed up the reaction

# data[].attributes.body
I think magnesium will be the most reactive.

# data[].attributes.body
i think that an increase in temprature would increase the rate of reaction

# data[].attributes.body
I think magnesium will be the most reactive metal.

# data[].attributes.body
I think that a higher temperature would increase the reaction rate. A higher temperature would mean more heat and energy, which means the bonds in the reactants would break faster. This would speed up the reaction.

# data[].attributes.body
Yes. The smaller the surface area the more reactions will occur. This is because there is less space for the reactants to travel to, therefore they are moving fast in a small face and will collide more.

# data[].attributes.body
I think aluminium is the most reactive because it has the highest electronegativity out of all the metals.

# data[].attributes.body
I think that the rate of reaction would increase when the temp increases as the particles have more kinetic energy, so they will be moving faster and bump into other particles quicker. If the temp decreases, the reaction rate decreases as the kinetic energy that the atoms and molecules contain is low, so they will take a longer time to react with each other.

# data[].attributes.body
A greater concentration of acid would speed up the reaction. This is because there is more acid for the metal to react with and to form the products.

Aluminum

# data[].attributes.body
An increase in temperature --> more reactions

# data[].attributes.body
I believe that heating up the temperature will speed up the reaction and the opposite for cooling the temperature.
Because of the increased temperature the particles would react more frequently and quickly which will cause the reaction to speed up. If the temperature is lowered then the particles would react less frequently and quickly causing a reaction that is slower.

# data[].attributes.body
The more reactant concentration the more likely a reaction will occur.

# data[].attributes.body
I think that the size increase/decrease of the surface area of Fe does indeed affect the rate of the reaction occurs. This is evident when having an increase in the surface area which leads to faster moving reactions/collisions and overall leads to a increased rate of reaction.

# data[].attributes.body
Increasing the concentration of the acid will increase the speed of the reaction as there are more particles the reactant can have a reaction with.

# data[].attributes.body
Increasing the temperature would result in a faster rate of reaction because thermal energy will cause the molecules in the acid to accelerate and react with the metal at a faster rate.

# data[].attributes.body
A greater concentration would mean that there is more reactants in the experiement which would result in the metal dissolving faster.

# data[].attributes.body
the higher the temperature, the faster the rate of reaction would be. This is because

# data[].attributes.body
If we increase the surface area then the rate of reaction would be less and vice versa for if we decreased the surface area. Because of this I claim that changing the surface area will either slow down or speed up the rate of reaction

# data[].attributes.body
I think that in increase in temp. leads to a quicker reaction rate
