Investigating the factors affecting the rate of a chemical reaction. Introduction: In my coursework I will be mainly concentrating on the reaction between dilute hydrochloric acid with marble chips (calcium carbonate). Calcium carbonate (marble chips) + hydrochloric acid ==> calcium chloride + water + carbon dioxide CaCO3(s) + 2HCl (aq) ==> CaCl2 (aq) + H2O (l) + CO2 (g) Aim: The aim of the experiment is to investigate how the concentration of hydrochloric acid affects the rate of reaction
