Calculation Of Percentage Feed Left Over As Liquid And Vapor

Question

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    


Summary

The question belongs to Chemistry and it discusses about calculating the percentage of feed left over as residue with fractions of benzene in liquid and vapor.
