Question

Volatile liquids A and B are completely miscible and form ideal solutions in all proportions. The pure vapor pressures at 298K are PA* = 500. torr and PB* = 200. torr. Using Excel may reduce the amount of time required to complete the following requested effort. Calculate, at 0.1 mole fraction intervals (x_A = 0, 0.1, 0.2, . . . , 1) PA, PB, Ptotal, and y_A, which is the vapor phase mole fraction of A. (i)Present these calculations in a suitable table. (ii)Plot PA, PB and Ptotal, vs. x_A, and plot Ptotal, vs. y_A on the same mole fraction scale as x_A. All four plots should superimposed on the same axes as in the adjacent figure, but with labels for the lines/curves.
