# According to the collision theory and model created to explain the collision theory, what is the best explanation for why a higher temperature makes a reaction go faster?

Temperature is a measure of the average kinetic energy of the molecules. Kinetic energy is $k e = \frac{1}{2} \times m {v}^{2}$ The greater the velocity of the molecules the greater the energy which the molecules collide. The greater the energy of the collisions the greater the likelihood that the collisions will result in a reaction.
