7. Refer to the boiling point diagram for butanol/acetone shown below (Compound A= acetone; B= butanol). A mixture containing 0.5 mole fraction butanol and 0.5 mole fraction acetone is distilled. ( 3 points) a. At what temperature would this solution begin to boil? How does this temperature compare with the boiling points of the pure compounds? b. What would be the composition of the first droplet of vapor which recondenses? How does this drop compare to the composition of the original liquid being distilled? c. How many times would you need to condense and re-evaporate the first vapor to obtain pure acetone
