Problem

A galvanic cell operates under standard conditions with a balanced overall reaction that transfers 2 electrons per formula unit. If the standard free-energy change for the reaction is ΔG∘=−2.37×105 J\Delta G^\circ = -2.37\times10^5\,\text{J}, what is the corresponding standard cell potential Ecell∘E^\circ_{\text{cell}}? (Assume F=9.65×104 C mol−1 e−F = 9.65\times10^4\,\text{C\,mol}^{-1}\,e^{-}.) (a) 2.46 V (b) 1.23 V (c) −1.23 V (d) 0.61 V
