1. Use the data given in the table below to construct atemperature-composition diagram for cyclohexane toluene mixture(see p. 134 in the textbook for an example of such plot). Based onyour plot, what is the composition of the distillate obtained bysimple distillation of 20 mole percent cyclohexane and 80 molepercent toluene? Show your work on the plot (submit your plot).

T ⁰C	Mol % Cyclohexane Liquid	Mol % Cyclohexane Vapor
110.7	0	0
108.3	4.1	10.2
105.5	9.1	21.2
103.9.	11.8	26.4
101.8	16.4	34.8
99.5	21.7	42.2
97.4	27.3	49.2
95.5	32.3	54.7
93.8	37.9	59.9
91.9	45.2	66.2
89.8	53.3	72.4
88	59.9	77.4
86.6	67.2	81.1
84.8	76.3	86.4

2. Refer to the plot you constructed in Q#1 to answer thisquestion. Estimate the composition of the distillate of the samemixture (20 mole % cyclohexane) if the distillation column hadthree theoretical plates. (Show your work on the plot)

3. What would be the minimum number of theoretical platesrequired to achieve 100% purification so that the distillatecontains 100 mole % cyclohexane. (Show your work on the plot)

4. The number of theoretical plates is crucial for a goodseparation inn fractional distillation, but is not the only factorthat would effect the results of the degree of separation. Give oneother factor that can contribute to the success of fractionaldistillation? Explain.
