The Flowsheet Calculator (Constant Type) displays enthalpy of formation as -110.530 kJ/mol for the Peng Robinson Model Set.
When Property enthalpyF is displayed, the value is -110.5388, which is Property Type enthalpy, -0.00879, plus Constant Type EnthalpyOfFormation, -110.530. This is understandable.
My question is what is the Property gibbsEnergy? I have a guess.
From COCO Help Entry
Gibbs free energy
"If TEA's internal calculation routines for enthalpy and entropy are used, the Gibbs energy will not include the formation terms (heat of formation and entropy of formation)."

Is this correct? Thanks for any information on this.
