Question
Use E5C.1(a) to Plot the data in excel. Place two data sets on the same graph: one for temp vs. x and one for temp vs y (remember, x and y are the mole fractions and they belong on the x-axis). Don’t forget to include the boiling points of the pure substances – they are data, too.
Add a trendline (polynomial, 3rd order should work) to each of the coexistence lines separately.
Scale the plot appropriately and use the graph to answer the questions.
Then complete E5C.1(b)
Transcribed Image Text:**E5C.1(a)** The following temperature–composition data were obtained for a mixture of octane (O) and methylbenzene (M) at 1.00 atm, where \( x \) is the mole fraction in the liquid and \( y \) the mole fraction in the vapour at equilibrium.
| θ/°C | 110.9 | 112.0 | 114.0 | 115.8 | 117.3 | 119.0 | 121.1 | 123.0 |
|------|-------|-------|-------|-------|-------|-------|-------|-------|
| \( x_M \) | 0.908 | 0.795 | 0.615 | 0.527 | 0.408 | 0.300 | 0.203 | 0.097 |
| \( y_M \) | 0.923 | 0.836 | 0.698 | 0.624 | 0.527 | 0.410 | 0.297 | 0.164 |
The boiling points are 110.6°C and 125.6°C for M and O, respectively. Plot the temperature–composition diagram for the mixture. What is the composition of the vapour in equilibrium with the liquid of composition (i) \( x_M = 0.250 \) and (ii) \( x_O = 0.250 \)?
**E5C.1(b)** The following temperature/composition data were obtained for a mixture of two liquids A and B at 1.00 atm, where \( x \) is the mole fraction in the liquid and \( y \) the mole fraction in the vapour at equilibrium.
(Note: To fully interpret this data on an educational website, students should be guided on how to plot the temperature-composition diagram and interpret the equilibrium states of the mixtures based on the provided mole fractions and temperatures.)
