ABSTRACT
The molar composition of the at equilibrium be calculated (7.69) as a function of its value fLi,o/RT, atomic make-up of its molecules. and a set of Lagrangian (which are detennined from the atomic The Lagrangian multiplier is called the elemental potential for the eth atom (or element). This can be seen from the rearranged form of Eq. (7.68):
(7.70)
in which Ae the Gibbs fl!nction f.Li/ RT per mole of eth species atoms. It is interesting to see that each atom of element contributes the same amount to the Gibbs function, regardless of which molecule or phase it may be in (Reynolds, 1986).
