Question

Build in Excel a liquid-vapor equilibrium diagram for the water-acetone system using Wilson's model and
Compare the data with the equilibrium data of Raoult's law.

Answer 1

The values of mole fraction of acetone in liquid phase (X) and vapor phase (Y) has been tabulated below:

X	Y (Wilson's Model)	Y (Raoult's Law)
0	0	0
0.1	0.694	0.277
0.2	0.752	0.469
0.3	0.777	0.607
0.4	0.794	0.71
0.5	0.812	0.788
0.6	0.831	0.85
0.7	0.855	0.899
0.8	0.887	0.939
0.9	0.931	0.972
1	1	1

The plot has been generated in excel for the two cases. The curve in blue is the one for Wilson's Model and the curve in red is the one for Raoult's Law.
