Richard Tandy March 2004 Year 11 Science Coursework An investigation into the effect of concentration on the rate of reaction. The disappearing cross experiment. Introduction The rate of reaction is a measure of the change, which happens during a reaction in a single unit of time. There are numerous variables that are specifically known to affect the rate of reaction, the most commonly known being: * Temperature - Temperature alters the rate of a reaction by supplying the reactant particles with more energy, the more energy the reactants have the faster they move around increasing their chance of bumping into one another and having a successful collision. Also the more energy they get from the heat the more particles have enough energy to react, this is known as activation energy. * The surface area (of solids) is another variable that affects the rate of reaction. For example a larger surface area will result in...
