= 6. TCM (tetrachloromethane) and TCE (trichloroethylene) form an ideal solution at 40 C at all concentrations. a. Given that the vapor pressure of TCM and TCE at 40 C are 214 torr and 138 torr, respectively, plot the pressure-composition diagram for this system (you may use a spreadsheet software, label properly). b. The vapor pressures of TCM and TCE between 76.8 C and 87.2 C can be expressed empirically by the formulas: 2790.78 In(Prcm) = 15.8401 T + 226.4 and 2345.4 In(Pice) = 15.0124 - T + 192.7 where T is in C and P* is in torr. Assuming ideal solution formation at all compositions, calculate mole fractions of the components in the solution and the gas phase at 82 C (at ambient conditions). c.
