The value of ΔG (kJ mol^–1) for the given cell is (take 1 F = 96500 C mol^–1) — Electrochemistry Chemistry Question

💡 Solution & Explanation

The Gibbs free energy change is given by the relation ΔG = -nFE. For M^2+, the number of electrons transferred is n = 2. ΔG = -2 × 96500 C/mol × 0.059 V = -11387 J/mol. Converting to kilojoules, ΔG = -11.387 kJ/mol, which approximates to -11.4 kJ/mol. Therefore, correct answer is D.
