Consider an equimolar mixture of acetone and methyl isobutyl ketone (MIBK). Acetone is the

more volatile component.

a. (15 points) Generate a Txy diagram for the acetone/MIBK mixture at 1 atm using Excels

Solver function. Use Table B.4 in Felder, Rousseau & Bullard to calculate the values of the

vapor pressures of both components using Antoines equation. Plot the dew point and the

bubble point curves in a single plot.

b. (5 points) Use the 4th order polynomial equation of the Trendline to fit the data and establish

the equations describing the dependence of the dew point (Tdp) and bubble point (Tbp) temperatures

on the mixture composition. Display the equations on the chart.

c. (5 points) Use Solver to solve the equations obtained in part b) and find the mole fractions of

acetone in the liquid and vapor phases at T=85C.

d. (10 points) Calculate the molar ratio of the liquid phase to the vapor phase (i.e., n(l)/n(v)) at

T=85C. You can use the level rule or normal balance equations.
