Suggest explainations for:
The increased speed of a simple bimolecular change when temperature of the reaction mixture is increased.
Temperature usually has a major effect on the rate of a chemical reaction. Molecules at a higher temperature have more thermal energy. Although collision frequency is greater at higher temperatures. When the temperature of reaction mixture is increased, the kinetic energy of molecules increases which results in increase in velocity of molecules which in turn, results in increase in number effective, collisions; Consequently the speed of bimolecular change get increased.
