If the potential of a voltaic cell is +1.20 V,what is the free-energy change when one mole of electrons is transferred in the oxidation-reduction reaction?

Question

Quizplus · Accepted Answer

The free-energy change (ΔG) is calculated using the formula ΔG = -nFE, where n is the number of moles of electrons, F is Faraday's constant (approximately 96485 C/mol), and E is the cell potential. For one mole of electrons and a cell potential of +1.20 V, ΔG = -(1 mol)(96485 C/mol)(1.20 V) = -115782 J, which is approximately -116 kJ.
