In UNIQUAC term, the excess molar volume, , is assumed to be analogous to that of the excess Gibbs energy, i.e.
where is a different interaction parameter from that of
in the
model.
The symmetrically normalized
(subscript UNIQ is omitted in the following text) needs to be converted to the unsymmetrically normalized value (
) for density calculations in MSE.
Conversion from
to
:
Standard state chemical potentials in the two normalizations are related by
(or
)
which is derived from equality of chemical potentials in two normalizations, and using
