The fraction of molecules that collide with a kinetic energy equal to the activation energy for a reaction decreases rapidly with an increase in temperature.

Question

Quizplus · Accepted Answer

The fraction of molecules that collide with a kinetic energy equal to the activation energy for a reaction actually increases with an increase in temperature. This is because the molecules move faster and have a higher kinetic energy at higher temperatures, which increases the likelihood of successful collisions. This is described by the Arrhenius equation.
