2b. To a very good approximation, the excess Gibbs energy for the system acetone (1)/ methanol(2) is given by & Bx, x GE RT The vapor pressure of acetone and methanol are given by Antoine equation 2795.817 In P, (kPa)=14.39155- +(C) +230,002 3644.297 In P2 (kPa)=16.59381 (C) +239.765 If B = 0.64 and the vapor phase is assumed an ideal gas, determine the equilibrium temperature and vapor composition at P = 175 kPa and x=0.4
