AP Chemistryeasymcq1 pt

The rate of a chemical reaction generally increases with temperature because:

A.The equilibrium constant increases

B.The order of the reaction changes

C.The activation energy decreases

D.More molecules have sufficient energy to overcome the activation energy barrier

Explanation

Core Concept

Increasing temperature increases the average kinetic energy of molecules, meaning more molecules have energy ≥ the activation energy. This leads to more frequent successful collisions and a faster reaction rate.

Correct Answer

DMore molecules have sufficient energy to overcome the activation energy barrier
