Consider one mole of a real gas (constant pressure heat capacity, Cp, of 32.52 J/K) expanded adiabatically and isenthalpically from 19.971 atm to 2.221 atm. The Temperature of the gas was 291.2799 K before expansion and 293.9809 K afterwards. What is the change in Enthalpy with respect to pressure at constant temperature,(δH/δp)T for this gas in J/atm?
