Consider a solution containing 5 moles of acetone and 5 moles chloroform. The vapor pressures of pure acetone and pure chloroform at 35°C are 345 torr and 293 torr, respectively.

Acetonitrile and dodecane are partially miscible liquids under certain conditions. The phase is diagram for this system is shown below. temperature, K 390 370 350 330 310 290 270 0 0.1 liquid-liquid phase diagram acetonitrile - dodecane 0.2 0.3 0.7 0.4 0.5 0.6 mole fraction of acetonitrile, Xaceto 0.8 0.9 1 a. Choose one temperature and mixture combination in which these two liquids will be miscible. Place that point on the graph, label it, and then list here the temperature and the mole fraction value is for that point. b. A solution is made by mixing 0.40 moles of acetonitrile and 0.10 moles of dodecane. At room temperature, 293 K, when mixed, you observe two liquid layers. What are the compositions of those two layers and which layer is larger (i.e. has more volume)?e non-spo c. A solution is made by mixing 0.40 moles of acetonitrile and 0.10 moles of dodecane. This solution is warmed to 350 K. At this temperature, what are the compositions of the two layers and which layer is…

The melting point of ice decreases as pressure increases. Use the pressure dependence of chemical potentials to explain this phenomenon.

Sketch a well-labelled typical phase diagram for a pure substance, and label all regions appropriately.
