Question

Assertion (A): A reaction can have zero activation energy.

Reason (R): The minimum extra amount of energy absorbed by reactant molecules so that their energy becomes equal to the threshold value is called activation energy.

In the light of the above statements, choose the correct answer from the options given below:

Options

• 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 but R is true.

• Both A and R are true and R is the correct explanation of A.

Answer 1

A is false but R is true.

Explanation:

Since a reaction cannot have zero activation energy. Therefore, E_a is the minimum extra amount of energy absorbed by reactant molecules so that their energy becomes equal to the threshold value.
