10.1-2 The binary mixture of benzene and ethylene chloride forms an ideal solution (i.e., one that obeys Raoult's law) at 49.99°C, as shown by the data of J. von Zawidzki

[Z. Phys. Chem., 35, 129 (1900)]. At this temperature pure benzene boils at 0.357 bar, and pure ethylene chloride boils at 0.315 bar. Develop the analogues of Figs. 10.1-1 to 10.1-3 for this system.
