Experiment: Establishing the factors which affect the rate of a chemical reaction. Introduction: Metal carbonates react with dilute with dilute acids to give off carbon dioxide gas. The rate of the reaction can be gauged by the amount of gas produced at certain time intervals. In this experiment I will investigate the reaction between calcium carbonate and hydrochloric acid and the factors affecting it. This is the formulaic equation for the reaction: Calcium carbonate + Hydrochloric › Calcium chloride + Water + Carbon Dioxide CaCO (s) + 2HCl › CaCl (aq) + H O (l) + CO (g) Factors affecting the rate of reaction: * The molar of the hydrochloric acid * The surface area of the calcium carbonate * Temperature * Amount of acid * Amount of calcium carbonate * Stirring of acid during experiment Preliminary work: In order to obtain a little more information on the effect of changing conditions of temperature, surface area and concentration on...
