Question

Enthalpy departure derivation

Answer 1

Answer:

Enthalpy departure is the dimensionless value of (h[ideal]-h)/(RTc). h[ideal]-h is the difference in enthalpy between an ideal gas and a real gas at the same temperature and pressure. R is the gas constant and Tc is the critical temperature.

Answer 2

Answer:

Common departure functions include those for enthalpy, entropy, and internal energy. ... A departure function gives the difference between the real state, at a finite volume or non-zero pressure and temperature, and the ideal state, usually at zero pressure or infinite volume and temperature.
