... we do P∆V work, where P is the equilibrium pressure PNH3 and ∆V is the volume of a mole of ideal gas at 473.15 K and PNH3 . Because P1V1 = P2V2 for ideal gas, the P∆V work done is identical to what it would be if P was 1 bar, because although the pressure is greater, the volume change is proportiona ...
