In general, as temperature rises, so does reaction rate. This is because the rate of reaction is dependent on the collision of the reacting molecules or atoms. As temperature rises, molecules or atoms respond with increased motion, increasing the collision rate, thus increasing the reaction rate.
Rate of reaction and changing conditions. The above graph summarises the differences in the rate of reaction at different temperatures, concentrations and size of solid pieces. The steeper the line, the greater the rate of reaction. Reactions are usually fastest at the beginning, when the concentration of reactants is greatest.
