JEE Main Chemistry question

The rate of reaction increases with temperature due to [OJEE 2008]

(A)Decrease in activation energy
(B)Increase in activation energy
(C)Increase in collision frequencyCorrect
(D)Increase in concentration

Answer: (C)

Solution

Activation energy is a fixed property of the reaction and does not change with temperature, and reactant concentration is unaffected by temperature alone. Raising the temperature increases the average kinetic energy of the
