During an experiment, 1.00 moles of argon gas (a real gas) undergoes a compression such that the final volume is ½ of the initial volume. The initial volume and temperature of the gas are 2.53 m3 and 298 K, respectively. After the compression is complete, the temperature of the gas is 215 K.
If the argon behaves according to the equations of state: P(V-nb) = nRT where, b = 0.115 m3/mol. and the molar heat capacity at constant pressure is Cp(T) = 20.785 +0.02630T (units of J/mol-K), what is the change in enthalpy?
