Type: MCQ-numerical-Medium-Class 12
G° for the reaction, Cu²⁺ + Fe → Fe²⁺ + Cu is (Given : E°{Cu²⁺/Cu} = +0.34 V, E°{Fe²⁺/Fe} = -0.44 V)
A
11.44 kJ
B
180.8 kJ
C
150.5 kJ
D
28.5 kJ
Correct Answer
Option C
Detailed Explanation
The Gibbs free energy change (G°) can be calculated using the formula G° = -nFE°cell. Substituting the given values, G° = 150.5 kJ.
