Problems 13.43 through 13.54 require parameter values for the Wilson or NRTL equation for liquid-phase activity coefficients. Table 13.10 gives parameter values for both equations. Antoine equations for vapor pressure are given in Table B.2, Appendix B.
13.46. For one of the binary' systems listed in Table 13.10. based on Eq. (13.19) and the .NRTL equation, prepare a txy diagram for P = 101.33 kPa.
Table 13.10: Parameter Values for the Wilson and NRTL Equations
Parameters a12, a21, b12 and b21 have units of cal+mol-1 and V1 and V2 have units of cm3+ mol-1
Values arc those recommended by Gmehling el al., Vapor-Liquid Equilibrium Data Collection, Chemistry Data Scries, vol. 1. parts la. lb. 2c. and 2c. DECHEM A. Franklurt/Main. 1981-1988.
