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.

For one of the binary systems listed in Table 13.10, based on Eq. (13.19) and the Wilson equation, make the following calculations:

(a) BUBL T : P = 101.33 kPa, \(x_{1}=0.3\).

(b) DEW T : P = 101.33 kPa, \(y_{1}=0.3\).

(c) P, T − flash : P = 101.33 kPa, \(T=\frac{1}{2}\left(T_{\text {bubble }}+T_{\text {dew }}\right), z_{1}=0.3\).

(d) If an azeotrope exists at P = 101.33 kPa, find \(T^{\mathrm{az}} \text { and } x_{1}^{\mathrm{az}}=y_{1}^{\mathrm{az}}\).
