| Comment | Activity coefficients model |
| Variable GEX | Excess Gibbs energy |
| Variable T | Temperature |
| Variable x1 | Mole fraction of component 1 |
| Variable x2 | Mole fraction of component 2 |
| Parameter a | Array (0 to nTerms) |
| Constant nTerms | Number of terms |
| Constant R | Gas constant |
GEX/(R×T) = Σai×x1×x2×(x1 - x2)i, where the summation is from i = 0 to nTerms.
