A liquid is fed to a distillation column at 4 atm absolute pressure. Its composition as a mole fraction is: n-butane: 0.40, n-pentane: 0.25, n-hexane: 0.20, n-heptane: 0.15. Using the equilibrium distribution coefficients (K), find the temperature at which this liquid will begin to boil (bubble temperature). Calculate the concentration of the first vapor bubble formed. K equilibrium distribution coefficient values are given in the table below.
