The reflux ratio is 1.5 and q=0.6

A distillation column with 100kmol/h feed of 50%A and 50%B produces a distillate product with xD=0.95 and a bottom stream with xbot=0.04 of the more volatile species A. CMO is valid and the equilibrium data is given by y=1+1.4x2.4x The mole fraction of A in the vapor stream entering the top equilibrium stage
