Rate of reaction. Reaction of chalk with 0.1 M hydrochloric acid is used to demonstrate that the rate of reaction depends on surface area. Chalk is calcium carbonate,it reacts with hydrochloric acid to produce carbon dioxide bubbles: CaCO3 + HCl -> CaCl2 + H2O + CO2. This is an example of a double displacement reaction. In left panel,a piece of chalk is placed in hydrochloric acid. In right panel,chalk is ground and the reaction rate is visibly higher | |
