What Affects the Rate of Reaction Between Hydrochloric Acid and Calcium Carbonate?

PLANNING:

For this experiment I am going to test how temperature affects the rate of reaction between hydrochloric acid and calcium carbonate. There were many variables that I could have chosen such as:

Factors:

Surface Area: This would have meant changing the area of the calcium carbonate by grinding it up into smaller pieces. E.g. from a lump, to chips, to powder. This would mean that there would be more surface area meaning a higher rate of reaction because there is a higher area of contact between the reactants. The acid can get to all the calcium carbonate quicker.

Concentration: This would have meant changing the concentration of the acid from 1 mole, to 1.5 mole, to 2 mole etc. This would increase the rate of reaction because there would be more acid in the experiment in relation to chalk, no matter what volume was in the beaker.

Temperature: This meant changing the temperature of the acid. If the temperature is increased, then the average speed of any one particl...
