Example 1 Phase Diagram & Equilibrium Curve

Use Raoult's Law and calculate the vapour and liquid compositions in equilibrium (in mole fractions, y and x) for the benzene-toluene system using vapour pressure data measure at a pressure of 101.32 kPa as shown in Table E-1 below :

Table E-1. Temperature-Vapour Pressure Data for Benzene-Toluene at 101.32 kPa

Vapour pressures for Benzene-Toluene

Next plot the phase diagram (T-x-y diagram) and equilibrium curve for the benzene-toluene system at 101.32 kPa
