Q. 28
How are most probable kinetic energy and the energy of activation affected with increase in temperature.
OR
Explain the difference between instantaneous rate of a reaction and average rate of a reaction.
Answer :
The most probable Kinetic energy and energy of activation affected with increase in temperature as according to Maxwell Boltzmann energy distribution curve when temperature T becomes T+10 degree Celsius then the effective collision and energy of molecules increases resulting in the formation of product.
OR
