The temperature effect on reaction rate is the result of which of the following?

Question

Quizplus · Accepted Answer

At higher temperatures, there are more collisions because the molecules have higher kinetic energy and move more rapidly. This is represented by choice A. Additionally, at higher temperatures a larger fraction of the collisions are effective because more of the collisions have sufficient energy to overcome the activation energy barrier and result in a reaction. This is represented by choice B. Therefore, both choices A and B contribute to the temperature effect on reaction rate.
