Problem 1: At 50 °C the system acetone(1) and chloroform(2) forms an azeotrope with composition x1 = 0.416.

a) What is the pressure at the azeotropic composition at 50 °C?

b) 1 mole of acetone is mixed with one mole of chloroform at 50 °C, 0.5 bar. What is the phase of the pure components before mixing? What is the phase of the system after mixing?

c) Do you expect the two liquids to be fully miscible at 50 °C or not?

Additional information: The activity coefficients are given by the following equations:

In γi = Axi2,

where A is an unknown constant. The saturation pressures of the pure components at 50 °C are: Pacetone =0.81 bar, Pchloroform = 0.41 bar.
