Coursework - An Investigation To Find Out How The Concentration Of Hydrochloric Acid Affects The Rate Of Reaction With Calcium Carbonate Background Knowledge I am doing this experiment to find out whether the concentration of hydrochloric acid affects the rate of reaction with calcium carbonate. In this experiment, when you add calcium carbonate (marble chips) to hydrochloric acid, carbon dioxide is given off. EQUATION CaCo3 + 2HCl CaCl2 + H2O +C02 Calcium Carbonate + Hydrochloric acid Calcium Chloride + Water + Carbon Dioxide. Collision Theory Because I am investigating the rate of reaction, I looked up some important notes on this. From the 'Co-ordinated SCIENCE Chemistry' book, I learnt that the rate of reaction is combined with the ' Collision Theory'. This is when particles react when they collide, due to their kinetic energy. The higher the concentration of particle, hence more chance of...
