'Investigating factors that affect the rate of chemical reactions.'

Chemistry Coursework

Scientific Knowledge.

The rate of a reaction is a measure of how fast the reaction between the reactants occurs and so how fast the products are produced. Some reactions are very slow, such as the rusting (oxidisation) of iron to ferrous oxide (rust) in the presence of water. Some reactions are very fast, such as the reaction between sodium metal and water or when dynamite explodes. Both these reactions would not be good for us to study as they occur too slowly or too quickly for us to measure accurately. A reaction that occurs at a reasonable rate should be studied, such as the reaction between dilute hydrochloric acid and calcium carbonate, in the form of marble chips or powder.

Calcium carbonate + hydrochloric acid calcium chloride + water + carbon dioxide

CaCO3(s) + 2HCl (aq) CaCl2 (aq) + H2O(l) + CO2(g)

Another advantage of this reaction is that carbon dioxide is a product. Carbon dioxide is a gas and thus the rate of reaction can be measured by
