Why do most chemical reaction rates increase rapidly as the temperature rise ?

Options

A. The fraction of molecules with kinetic energy greater than the activation energy increases rapidly with temperature
B. The average kinetic energy increases as temperature rises
C. The activation energy decreases as temperature rises
D. More collisions take place between particles so that the reaction can occur

Answer

A

Explanation

As the temperature rises , the molecules gain more kinetic energy and more number of collisions takes place leading to speeding up of reaction i.e., increasing the rate of reaction .
