NEET Chemistry (general) MCQ Question
Type: MCQ-numerical-Medium-Class 11
Calculate the Gibbs free energy change (∆G ) for a reaction with an equilibrium constant (K) of 10 at 300 K. Use R = 8.314 J K⁻¹ mol⁻¹.
A
-5.71 kJ/mol
B
-7.61 kJ/mol
C
5.71 kJ/mol
D
7.61 kJ/mol
Correct Answer
Option A
Detailed Explanation
The Gibbs free energy change ∆G is related to the equilibrium constant by the equation ∆G = -RT ln K. Substituting the given values, ∆G = -8.314 * 300 * ln(10) = -5.71 kJ/mol.
