Increasing the temperature of a chemical reaction usually increases greatly the rate of the reaction.The most important reason for this is that increasing the temperature:

Question

Quizplus · Accepted Answer

Increasing the temperature increases the kinetic energy of the particles, which enhances their ability to overcome the activation energy barriers. As a result, a larger fraction of molecules will have energy greater than the activation energy threshold and will be able to react when they collide. Therefore, the higher temperature increases the fraction of collisions with energy greater than the activation energy (E_act), which significantly boosts the reaction rate.
