The expansion work on an irreversible system is equal to:
W = - PV
Assuming that the gas is ideal, therefore:
PV = nRT
[P=pressure, V=volume, n=number of moles, R=gas constant,
T=absolute temperature]
Therefore,
W = -nRT
W = -(1 mol) * (8.314 J / mol K) * (1250 K)
W = -10,392.50 J
Therefore about 10,392.50 J or 10.4 kJ of work is done on
the system.
