AIIMS 2017 Chemistry Activation Energy MCQ Question
Consider the below given figure.
The correct option for the above presentation is
activation energy of forward reaction is + and product is less stable than reactant
activation energy of forward reaction is + and product is more stable than reactant
activation energy for both forward and backward reaction is reactant and reactant is more stable than product
activation energy for the backward direction is and product is more stable than reactant
Correct Answer
Detailed Explanation
Option B is correct because it indicates that the products of the reaction have a higher energy level than the reactants, reflecting the stability of the reactants compared to the products. This aligns with the graph's depiction of activation energy, where the energy barrier (E₁ + E₂) must be overcome for the reaction to proceed, illustrating that the reactants are more stable. Other options may incorrectly suggest that the products are more stable or misinterpret the relationship between activation energy and the energy levels of reactants and products, leading to confusion about the thermodynamic stability of the substances involved.
