Reported the parameters of Wilson equation for ethanol(1)+n-hexane(2) system are A12=0.0952 and A21=0.2713. Antoine constants of pure substances may be found from elsewhere i.e. NIST.

a) find bubble point pressure and vapor composition at temperature 58 deg. C and x1=0.4

b) find dew point temperature and liquid composition at 1 atm pressure and y1=0,36

c) find vapor and liquid compositions and the vapor fraction when the equi molar mixture of etanol(1)+ acetone(2) is flashed to 60 deg. C and 1 atm.
