To simplify things we will generally restrict our examples to binary mixtures of two components or species. The situation is then as illustrated below.
The variables in the equations are, if we exclude the k_{i} which we
do not have to use:
The 6 relevant equations may be written as:
P^{*}_{1} - P^{*}_{1}(T) = 0 | (2) |
P y_{1} - x_{1} P^{*}_{1} = 0 | (3) |
P^{*}_{2} - P^{*}_{2}(T) = 0 | (4) |
P y_{2} - x_{2} P^{*}_{1} = 0 | (5) |
x_{1} + x_{2} - 1 = 0 | (6) |
y_{1}+ y_{2} - 1 = 0 | (7) |
