SUMMARY
The Margules' 3 suffix equations for binary solution derivation are defined as ln gamma1 = [A12 + (B12 - A12)x1](x2)^2 and ln gamma2 = [B12 + (A12 - B12)x2](x1)^2. These equations are derived from the model for excess Gibbs energy, allowing for the calculation of activity coefficients by differentiating the excess free energy model with respect to the number of moles of component i, while maintaining constant temperature and pressure. Understanding these equations is crucial for accurately modeling binary solutions in thermodynamics.
