The rate of reaction increases considerably with an increase in temperature. The rates of many reactions are approximately doubled or tripled for every 10 o C rise in temperature. The temperature coefficient of a chemical reaction is defined as the ratio of the specific reaction rates of a reaction at two temperature differing by 10 o C.
