    A feed of 50 mole % hexane and 50 mole % octane is fed into a pipe still through a pressure reducing valve and then into a flash disengaging chamber. The vapor and liquid leaving the chamber are assumed to be in equilibrium. If the fraction of the feed converted to the vapor is 0.5, find the compositions of the top and bottom products. The following table gives the equilibrium data for this system.
    Mole fractions of hexane in liquid x 1.00 0.69 0.40 0.192 0.045 0.00
    Mole fractions of hexane in vapor y 1.00 0.932 0.78 0.538 0.1775 0.00

    Please see the attached file for the fully formatted problem.
