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∘=−2.37×105J, what is the corresponding standard cell potential Ecell∘? (Assume F=9.65×104Cmol−1e−.)
a) 2.46 V
b) 1.23 V
c) −1.23 V
d) 0.61 V
