Q.
Consider the given figure and choose the correct option: [2025]

1 Activation energy of both forward and backward reaction is $E_{1} + E_{2}$ and reactant is more stable than product.

2 Activation energy of backward reaction is $E_{1} + E_{2}$ and product is more stable than reactant.

3 Activation energy of backward reaction is $E_{1}$ and product is more stable than reactant.

4 Activation energy of forward reaction is $E_{1} + E_{2}$ and product is less stable than reactant.

Ans.
(4)

Difference between energy of reactant and energy of activated complex ( $E_{1} + E_{2}$ ) is activation energy of forward reaction. More is energy, lesser is the stability. Product has higher energy than reactant hence it is less stable than reactant.
