###### Question details

Over a certain range of P and T, the PvT properties of a gaseous substance were found to be given with a reasonable accuracy by the following equation of state:

P v = RT+BP

Starting with the fundamental equations, derive expressions for the isothermal change of: (1) h and (2) g with P in terms of P, T, and B only. Let initial and final pressures be P1 and P2 respectively.
