An increase in the temperature at which a reaction is carried out increases:

Question

Quizplus · Accepted Answer

An increase in temperature increases both the collision frequency (due to increased molecular speed) and the fraction of molecules with energy greater than the activation energy (due to increased kinetic energy). Both of these factors contribute to an increase in the reaction rate. The fraction of molecules with proper orientation is not affected by temperature, as proper orientation is determined by the geometry of the reactants and is not affected by kinetic energy.
