How is activation energy affected by a rise in temperature.

Text Solution

Verified by Experts

Activation energy is the energy that the colliding molecules must possess to form the activated complex. It remains unaffected by rise in temperature. With rise in temperature it is more number of molecules that will possess the activation energy.
