Background

When molecules bump into each other, the kinetic energy that they have can be converted into chemical potential energy of the molecules. If the potential energy of the molecule becomes great enough, the activation energy of a reaction can be archived and a change in chemical state will result. Thus the greater the kinetic energy of the molecules in a system, the greater the resulting chemical potential energy. As the temperature of a system is increased it is possible that more molecules per unit time will reach the activation energy (2). Therefore the rate of reaction will increase. On the other hand if the temperature reaches a certain amount the enzyme might denature and therefore no longer able to carry out the reaction.
