Plot Vapor Liquid Equilibrium For Component

Question

The equilibrium concentration of component A of in the vapour phase y_A, with concentration of component A in liquid phase, X_A, can be given by:

y_A = x_AP_A^o/P

and

x_A = (P - P_B^o)/ (P_A^o – P_B^o)

where P = system pressure

P_A°, P _B° = saturated pressure of component (A) and (B) respectively.

(a) Briefly indicate the laws used to obtain these relationships.

(b) Plot the Vapour Liquid Equilibrium (VLE) curve (x_A, y_A) using the data given in Table Q5 and assuming that the benzene - toluene system will be maintained under an absolute pressure of 760 mmHg.

TABLE Q5

Summary

The question belongs to Chemical Engineering and it discusses about plotting Vapor Liquid Equilibrium for a component in liquid phase and vapor phase.
