The azeotrope of a binary mixture, being an important point on a mixture phase diagram, is often used for parameter estimation. To that end, use the azeotropic information for the acetone (1) + cyclohexane (2) system at 308.15 K to deter mine the A parameter of the 1-parameter Margules equation. Then plot the Pxy predictions from this model and compare it to the experimental data in Table P11 20. Note that you will need to plot the experimental data first to estimate the location of the azeotrope
