A pure gas obeys the equation of state given by PV/RT = 1 + BP/RT where P is the pressure, T is the absolute temperature, V is the molar volume of the gas, R is the universal gas constant, and B is a parameter independent of T and P. The residual molar Gibbs energy, GR, of the gas is given by the relation GR/RT = ∫0P(Z-1)dP/P where Z is the compressibility factor and the integral is evaluated at constant T. If the value of B is 1×10-4 m3mol-1, the residual molar enthalpy (in J mol-1) of the gas at 1000 kPa and 300 K is
