The reason for almost doubling the rate of reaction on increasing the temperature of the reaction system by `10^(@)C` isA. The value of threshold energy increasesB. Collision frequency increasesC. The fraction of the molecules having energy equal to threshold energy or more increasesD. Activation energy decreases

Answer» Correct Answer - c
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 .
