The reason for almost doubling the rate of reaction on increasing the temperature of the reaction system by 10^(@)C is

Answer»

The VALUE of threshold energy INCREASES
Collision frequency increases
The fraction of the molecules having energy equal to threshold energy or more increases
ACTIVATION energy decreases

Solution :When the temperature is INCREASED , heat energy is supplied which increases the kinetic energy of the reacting molecules . This will increase the number of collisions and ultimately the rate of REACTION will be enhanced .
