Reaction rates increase with temperature mainly because a rise in temperature increases

Question

Quizplus · Accepted Answer

Increasing the temperature increases the kinetic energy of the molecules, which increases the number of activated molecules that can overcome the activation energy barrier and react. Increasing temperature does not affect the number of ions or polar molecules, and it decreases the average length of time between molecular collisions.
