(1) Acetone is mixed with (2) methanol to a total composition of 25 mol% acetone. Activity coefficients can be described by the following formulas: Iny₁ = 0.64 x² . Iny2 = 0.64 x² . The mixture is cooled into the two-phase region at 1 bar. If the composition of the liquid product must be 17.5 mol%, what is the final temperature in Celsius and the vapor phase concentration of acetone as a percentage? What percentage of the feed mixture is recovered as a vapor?

Question
(1) Acetone is mixed with (2) methanol to a total composition
of 25 mol % acetone.
Activity coefficients can be described by the following
formulas:
InY₁ = 0.64 x²
InY2
0.64 x²
The mixture is cooled into the two-phase region at 1 bar.
If the composition of the liquid product must be 17.5 mol%,
what is the final temperature in Celsius and the vapor phase
concentration of acetone as a percentage? What percentage
of the feed mixture is recovered as a vapor?
