Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Threshold energy of reactants is less than that of products in reversible endothermic reactions hence. $E_{a}$ for forward reaction is more than $E_{a}$ for backward reaction.
