The Txy diagram for acetone/ethanol system at \( 1.01 \) bar is provided in the following figure. a. A 75 -mole mixture that is \( 40.0 \mathrm{~mol} \% \) ethanol at \( 70^{\circ} \mathrm{C} \) is cooled at constant pressure. At what temperature will the first liquid bubble form from this mixture? b. The mixture in (d) is further cooled to \( 63{ }^{\circ} \mathrm{C} \). What is the condition of the solution at this temperature? What is the amount and composition of the liquid and/or vapor phases formed from the mixture at this temperature? c. At what temperature will the last drop of vapor from the mixture condense?
