JEE Main Chemistry question

For a reaction, the rate of reaction was found to increase about 1.8 times when the temperature was increased by 10°C. The increase in rate is due to:

(A)Increase in number of active moleculesCorrect
(B)Increase in activation energy of reactants
(C)Decrease in activation energy of reactants
(D)Increase in the number of collisions between reacting molecules

Answer: (A)

Solution

Raising the temperature increases the fraction of molecules possessing energy at or above the (fixed) activation energy — i.e. it increases the number of
