The table below shows the % compositions of the vapor and liquid phases at equilibrium for solutions of A and B at the indicated temperatures: 1 Temperature (°C) 70 75 80 85 %Aìn vapor 100 97 93 85 %Ain liquid 100 79 65 95 100 105 110 115 120 69 60 50 40 25 45 37 28 20 12 6 a. Construct a vapor-liquid phase diagram for this system. Be quantitatively accurate. A computer-generated graph is recommended for full credit. Attach your labeled graph at the end of these questions. What is the molar composition of the vapor in equilibrium with a boiling liquid that has a composition of 70% A and 30% B? b. A sample of vapor has the composition of 60 % A and 40 % B. What is the composition of the boiling liquid that produced this vapor? c. What is the boiling point of a liquid having a molar composition of 50% A and 50% B? d. If you have a solution that is 50% A and 50% B, how many theoretical plates are needed to achieve a minimum purity of 95% A? Write your answer on the blank to the right, and show how you determined this answer by illustrating the cycles on the graph you created in part a. e.
