For a redox process transferring

n = 3

electrons, the standard free energy change is

\Delta G^\circ = +180\,\text{kJ mol}^{-1}

at 298 K. Determine the minimum magnitude of external voltage that must be applied per cell to drive this reaction under standard conditions (use

F = 96\,485\,\text{C mol}^{-1}

), and classify the cell as galvanic or electrolytic when operating with this applied voltage.
