Ideal gas heat capacity coefficients-pseudocomponents

Ideal gas heat capacity coefficients-pseudocomponents

(OP)
Where can I find coefficients to calculate ideal gas heat capacities for psuedocomponents from critical pressure, critical temperature and molecular weight?

RE: Ideal gas heat capacity coefficients-pseudocomponents

Your question is not clear to me.  Ideal gas  pv=nRT

Ideal gas heat capacities will be solely dependent upon specific heat variation with temperature.

How does pseudo critical enter into this?

RE: Ideal gas heat capacity coefficients-pseudocomponents

(OP)
The pseudocomponents are "lumps" of components (usually heavy ends) and the critical properties of the psuedocomponents are determined in the lab.  I need to calculate ideal gas heat capacity/enthalpy for the "lump" to get to the enthalpy departure. I think the GPA has some sort of correlation to predict the ideal properties from the critical properties and the MW but I can't remember where to find it. It may be a "senior" moment or a "blonde" moment but I'm stumped at the moment.
