Essay title: What Affects the Rate of Reaction?

What affects the Rate of Reaction?

The reaction I will use for this test is:

2HCl(aq) + CaCO3(s) CaCl2(aq) + CO2(g) + H2O(l)

The possible variables for this experiment are the concentration of acid; the surface area of the solid reactant, the calcium carbonate by using chips or powder; and the temperature. Following are quick summaries on how changing each variable will affect the rate of the reaction.

By increasing the surface area you are increasing the amount of collisions that will take place in a section of time therefore increasing the rate of reaction. The use of powder calcium carbonate will give a larger surface area so that the rate of reaction will increase because the collision, where two different molecules bump into each other, has to happen at the liquid solid interface if the liquid solid interface is larger then more collisions will take place in a period of time making the reaction
