NEET 2015 Physics Gibbs Free Energy MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Which of the following statements is CORRECT for a reversible process in a state of equilibrium?
A
ΔG° = –2.30 RT log K
B
ΔG° = 2.30 RT log K
C
ΔG = –2.30 RT log K
D
ΔG = 2.30 RT log K
Correct Answer
Option B
Detailed Explanation
At equilibrium, the change in Gibbs free energy (ΔG) is zero, and ΔG° is related to the equilibrium constant by ΔG° = –RT ln K.
