# 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?

Jan 3, 2018

Because the higher the kinetic energy the more collisions take place and the more energy the collisions have making them more effective.

#### Explanation:

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.

Also the velocity of the molecules means that more collisions will take place. If there are more collisions there is a greater likelihood that reactions will take place.
