Investigating the effect that concentration has on the reaction between hydrochloric acid and calcium carbonate Aim I plan to investigate the rate of reaction between hydrochloric acid and calcium carbonate. I will test how the acid concentration will affect the rate of reaction. Hypothesis I predict that the higher the concentration of acid then the faster the rate of reaction. Calcium Carbonate + Hydrochloric Acid => Calcium Chloride + Carbon Dioxide + Water CaCO3 + 2HCl => CaCl2 + CO2 + H2O Collision Theory Particles have to collide to react. They also have to collide hard enough. Therefore the rate of reaction simply depends on how often and how hard the reacting particles collide with each other. As I am experimenting how the concentration of acid affects the rate of reaction, I am going to explain how this is so. 0.5M 1.0M 2.0M Doubling the concentration Increase in HCl (more particles of HCl in the...
