Question

Vapor–liquid equilibrium for heptane–toluene system.
(a) The vapor pressure of toluene is given in Exercise 4.8, and that of n-heptane is in the table below. Construct the following plots:(a) an x–y diagram at 1 atm using Raoult’s and Dalton’s laws; (b) a T–x bubble-point curve at 1 atm; (c) a and K-values versus temperature; and (d) repeat of part (a) using an average value of a. Then, (e) compare your x–y and T–x–y diagrams with the following experimental data of Steinhauser and White.
