Many factors effect reaction rates, two shown above include temperature and concentration concentration affects the rate of reactions because the more concentrated a solution the more likely collisions between particles will be. The central approach for studying the mechanism of an enzyme-catalysed reaction is to determine the rate of the reaction and its changes in response with the changes in parameters such as substrate concentration, enzyme concentration, ph, and temperature etc this is known as enzyme kinetics.
