I have a code for the attached paper, the z in the code is I think alph^r (equation 42 in the paper) How can I find:

1. Predict isobaric and Isochoric heat capacity vs. temperature and density
2. Predict entropy vs. temperature.
3. Predict Speed of sound
4. Predict the latent heat of vaporization vs. temperature. And compare it with Peng-Robinson
