Textbook Question
Chapter 12.7, Problem 15P
Consider the 1,1,1- trifluoroethane [R-143a] (1) + n-butane (2) system at 508C. Using a gamma-phi modeling approach, calculate the Pxy diagram for the system using the 2-parameter Margules equation and the virial equation. Compare the predicted values with the experimental data provided in Table P12-15 (on the same plot). Also, please provide two additional modeling approaches to the plot.

- 1. Model the system using modified Raoult’s Law (ideal gas for the vapor). This includes calculating the activity coefficients assuming an ideal gas for the vapor (as in Chapter 11).
- 2. Model the system using Raoult’s Law.
