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

Question:

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, x₁ = 0.3.
(b) DEW T : P = 101.33 kPa, y₁ = 0.3.
(c) P, T − flash: P = 101.33 kPa, T = ½ (T_bubble + T_dew), z₁ = 0.3.
(d) If an azeotrope exists at P =101.33 kPa, find T^az and x^az₁ = y^az_1.

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.
