Describe how collision theory explains an increase in the rate of a reaction at higher temperatures.

When temp increases, kinetic energy of molecules increases. Higher kinetic energy means molecules move around more and increased movement leads to more collisions. Collision theory states that the rate of reaction is proportional to the number of collision so therefore rate of reaction increases. (It is assumed that these collisions will meet the activation energy for the reaction)
