ΔG = -nFE°cell. Calculate ΔG for E°cell = 0.24 V, n = 2.

1. -46.32 kJ/mol
2. -23.16 kJ/mol
3. -92.64 kJ/mol
4. None of the above

Correct answer: -23.16 kJ/mol

Solution

The formula ΔG = -nFE°cell is used, where F = 96500 C/mol. Substituting values: ΔG = -(2)(96500)(0.24) = -46320 J/mol = -46.32 kJ/mol. Hence, the correct answer is A.
