Have a little read: ... Our assignment was to produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them. The rate of reaction is the speed of a chemical reactions, usually used in terms of the concentrations of reactant consumed in a given time. What could affect the rate of a reaction * Temperature * Concentration (of solution) * Surface are (of solid reactants), * And Catalyst I have chosen to investigate the effect the concentration will have on the rate of reaction. This is because it is the easiest and the most practical to investigate - *it would take longer to prepare a solid in powdered and unpowdered form, *it is difficult to get accurate readings due to the probability of human errors, *the use of a catalyst complicates things, and if used incorrectly could affect the end results. Aim: - To see the effects of a change in concentration on the rate of a reaction.
