Activity coefficient and the excess Gibbs energy

The Margules equation models the excess Gibbs free energy by a two-parameter Redlich-Kister polynomial. The excess Gibbs energy and the activity coefficients are given by the following equations ... [Pg.431]

For an ideal mixture the excess part is equal to zero, since the activity coefficient is Yi = 1. From this definition, the connection between the excess Gibbs energy and the activity coefficient can be seen clearly ... [Pg.162]

The temperature dependence of the excess Gibbs energy and the activity coefficients can be derived from a g -h -diagram (Figure 5.21). Depending on the sign of the excess properties g and four quadrants are obtained. ... [Pg.205]
