NEET Chemistry Activation Energy Assertion Reason Question
Assertion (A): The rate of a chemical reaction increases with an increase in temperature.
Reason (R): Increasing temperature decreases the activation energy of the reaction.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
According to the Arrhenius equation, the rate of a reaction increases with an increase in temperature because a higher temperature increases the fraction of molecules with energy greater than the activation energy, not because the activation energy itself decreases.
