Background Information Rates of Reaction; The rate of reaction is the rate at which two substances react with each other. These are the variables affecting rates of reaction- * The concentration of the reactants, the more concentrated the shorter the time it takes to react, as there are more particles to react. * The surface area of the reactants, the larger the surface area the shorter the time it takes to react as there are more particles that the other reactants have contact with. Only the particles on the surface can react, if more are exposed more can react in the same period of time. * In a gas reaction if you increase the pressure the rate of reaction is increased because there are more particles to the same volume. * The higher the temperature of the reactants the shorter the time taken to react because particles gain more energy and move around more (see collision...
