Planning (Also see Investigation Planning Sheet.) Background Information I have been set a task to investigate factors which affect rates of reaction, using calcium carbonate and hydrochloric acid. These are good reactants to use, as carbon dioxide (CO2) is produced and this release of gas can be monitored using a gas syringe. Calcium + Hydrochloric Calcium + Water + Carbon carbonate acid chloride dioxide CaCO3 + 2HCl CaCl2 + H2O + CO2 What affects the rate of reaction? Rates of reaction can be explained using the Collision Theory, which has two main principles: * Particles must collide before a reaction can take place. * Particles must collide with enough energy for a reaction to take place. If particles collide and react, then a successful collision has taken place. However, if particles collide, but without enough energy to react, then an unsuccessful collision has taken place. There are four main factors that affect rates of reaction, and these can all be...
