interaction parameters

[thubelihle]

Hi sir. Do binary interaction parameters have units. l tried to derive it and l obtained the units being the inverse of R, the gas constant. But most literature when giving these values only state the units of temperature.

Temperature dependent binary interaction parameters are either in cal/mol, J/mol or K (the gas constant being indeed the translation between these units). In which application are you attempting to enter values?

Was trying to get them from aspen to COFE. Thank you
