Calculate ΔG° for a voltaic cell with E° = +0.24 V if the overall reaction involves a 3 electron reduction.(R = 8.31 J/K⋅mol,F = 96480 C/mol e−)

Question

Quizplus · Accepted Answer

ΔG° = -nFE°, where n is the number of moles of electrons, F is the Faraday constant (96480 C/mol e−), and E° is the standard cell potential (+0.24 V). For a 3 electron reduction, n = 3. Thus, ΔG° = -3 * 96480 C/mol * 0.24 V = -69475.2 J/mol ≈ -69 kJ.
