Question

Assertion A: An increase of temperature of a chemical reaction at constant pressure, the equilibrium value of the reaction shifts in the direction in which the heat of reaction absorbed.
Reason R: To minimize the Gibbs free energy change due to increase in temperature, the heat of reaction needs to be absorbed by shifting the equilibrium value.
In the light of the above statements, choose the most appropriate answer:

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Remember: Increasing temperature favors the Endothermic direction ($\Delta H > 0$), while decreasing temperature favors the Exothermic direction ($\Delta H < 0$).

Answer 1

The Correct Option is A
