a. Using the temperature-composition diagram, prepare the corresponding y – x diagram. Your diagram should show the data points. b. Consider a liquid feed mixture of 91 mol acetone and 169 mol cyclohexane. Using the T - x, y diagram, determine the bubble point temperature Tbubble, and vapor and liquid compositions of acetone at Tbubble. Determine the dew point temperature Tdew for a vapor feed mixture of the same composition, and vapor and liquid compositions of cyclohexane at Tdew. c. The feed in Part b is heated until the vapor has 54 mol% acetone. Use your temperature- composition diagram to determine the composition of the liquid phase, the temperature of the mixture, and the amounts of liquid and vapor (in mol.)

a. Using the temperature-composition diagram, prepare the corresponding y – x diagram.
Your diagram should show the data points.
b. Consider a liquid feed mixture of 91 mol acetone and 169 mol cyclohexane. Using the T–
x, y diagram, determine the bubble point temperature Tbubble, and vapor and liquid
compositions of acetone at Tbubble. Determine the dew point temperature Tdew for a
vapor feed mixture of the same composition, and vapor and liquid compositions of
cyclohexane at Tdew.
c. The feed in Part b is heated until the vapor has 54 mol% acetone. Use your temperature-
composition diagram to determine the composition of the liquid phase, the temperature of
the mixture, and the amounts of liquid and vapor (in mol.)
