Medium· Activation Energy· +4 / −1
Given below are two statements : one is labelled as **Assertion A** and the other is labelled as **Reason R** :
**Assertion A :** A reaction can have zero activation energy.
**Reasons R :** The minimum extra amount of energy absorbed by reactant molecules so that their energy becomes equal to threshold value, is called activation energy.
In the light of the above statements, choose the **correct** answer from the options given below :
