With reference to the P-x-y phase diagram in Figure 2.1 below, consider the following experiment: You begin with 100% mol of carbon tetrachloride at 35°C, 0.35 torr and add methanol dropwise at constant temperature and pressure until the mixture contains 99% by mol methanol. Describe all phase changes observed along this path and report the composition of methanol (in mole fraction) at the point where a phase change is observed. Label those points by using capital letter starting from A to the last drop where the mixture contains 99% mol of methanol. Note: Start at a point where you have 1 mole of CCl4 (pure). pressure (Torr) 0.50 0.45- 0.40 0.358 0.30 0.25- 0.20 0.0 0.2 1 methanol (1)/CC14 (2) 35 °C 8 0.4 0.6 0.8 mole fraction of methanol Figure 2.1 P-x-y diagram for the system methanol(1)/ CCl4(2) system 35°C. 1.0 Total [10]
