A liquid mixture containing 50 mole% n-heptane and 50 mole% n-octane is subjected to a differential distillation at atmospheric pressure until the residual liquid contains 30 mole% n-heptane. Using the equilibrium data determine the percentage of feed that is left over as residue. x and y are mole fractions of benzene in liquid and vapor.
x 0.50 0.46 0.42 0.38 0.34 0.32
y 0.69 0.65 0.61 0.57 0.52 0.49
