Question

Consider the given figure and choose the correct option: \includegraphics[width=1\linewidth]{322.png}

• A. Activation energy of both forward and backward reaction is \( E_1 + E_2 \) and reactant is more stable than product.
• B. Activation energy of backward reaction is \( E_1 \) and product is more stable than reactant.
• C. Activation energy of forward reaction is \( E_1 + E_2 \) and product is less stable than reactant.
• D. Activation energy of forward reaction is \( E_1 + E_2 \) and product is more stable than reactant.

Hint:

In energy diagrams, the activation energy for the forward reaction is measured from the reactant to the activated complex, and the activation energy for the reverse reaction is measured from the product to the activated complex.

Answer 1

The Correct Option is D

In the given reaction coordinate diagram: - \( E_1 \) represents the activation energy of the forward reaction. - \( E_2 \) represents the activation energy of the reverse reaction. - The total energy for the forward reaction is \( E_1 + E_2 \), and the product is more stable than the reactant as indicated by the lower position of the product compared to the reactant on the energy scale. Thus, the correct option is option (4).
