The effect of temperature on rate of reaction is just one of the things that can affect how a reaction proceeds, that is, how quickly whatever reactants are present become transformed into products. Of course, many of these factors are active at all times and can have competing influences o...

At higher temperature, average energy of the reactant molecules is greater. Hence, larger fractions of colliding molecules can cross the energy barrier and, therefore, the rate is faster.
Chemical reaction rates are influenced by several factors. Temperature is one of the most important factors. As the temperature increases, the rate of a chemical reaction generally increases. This is because at higher temperatures, the molecules have more kinetic energy. They move faster and collide...
With rise in temperature, the energy possessed by the reacting species increases. As a result, more species are in a position to cross the activation energy barrier. Therefore, the reaction rate increase with rise in temperature.
