The E^(o) for half cells Fe//Fe^(2+) and Cu//Cu^(2+) are –0.44 V and +0.32 V respectively. Then which of these is true?

A diatomic ideal gas is used in a Carnot engine as theworking substance. If during the adiabatic expansion part of the cycle the volume of the gas increases from V to 32 V, the efficiency of the engine is
