Given the set of VLE experimental data for the non-ideal mixture propane/n-pentane at 344.26 K from B. Sage and W. Lacey, “Phase equilibria in hydrocarbon systems, propanen- pentane system,” Industrial and Engineering Chemistry, 32, (7), 992–996, 1940,

correlate them with the Margules equations and make the T–xy chart at P = 400 kPa under the assumption that the vapor phase obeys the ideal gas law, while the liquid is a non-ideal liquid mixture.
