Question:
The activation energy for a simple chemical reaction A → B is Eₐ in the forward direction. The activation energy for reverse reaction
The activation energy for a simple chemical reaction A → B is Eₐ in the forward direction. The activation energy for reverse reaction
Show Hint
Reverse activation energy equals forward activation energy plus enthalpy change.
Updated On: Mar 18, 2026
- is always less than Eₐ
- can be less than or more than Eₐ
- is always double of Eₐ
- is negative of Eₐ
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Activation energy depends on enthalpy change of reaction.
Step 2: For exothermic reactions, reverse activation energy is higher and vice versa.
