4) A packed distillation column is used to separate methanol from water. At an intermediate height within the packed column, the mole fraction of methanol in the bulk of the vapour is 0.6 and the mole fraction of methanol in the bulk of the liquid is 0.4. Using the xy diagram overleaf, determine the molar flux of methanol from liquid to vapour at this vertical position in the column, given the film mass transfer coefficients, kG=0.1 mol m-2 s-1 and kL=0.05 mol m-2 s-1 . ANSWER =>>> xA *=0.28; yA *=0.67; NA=0.006 mol m-2 s-1 Steps on how to reach this please
