... Investigating Reaction Rates Aim: I am investigating the rate of a reaction, which is between calcium carbonate and hydrochloric acid, and to do this I have chosen the concentration of the acid as my variable for the experiment. The products of a reaction between calcium carbonate and hydrochloric acid is calcium chloride, carbon dioxide and water. CaCo3 + 2HCL = CaCL2 + H2O + CO2 So to measure the rate of reaction I will be measuring the time it takes to produce a certain amount of carbon dioxide. But to make the experiment fair I have to fix all of the other variables that affect my results. Variables Surface area of solid - The surface area has an effect on the rate of reaction as the larger the surface area of a solid the more opportunities there are for collisions to occur with the liquid. If the surface area is small, collisions can
