Consider a binary mixture of species 1 and species 2 that exhibit an azeotrope at
40 ºC. Their saturation pressures are 68.8 and 46.5 kPa, respectively. The liquid phase non-ideality can
be described by the one constant Margules equation, with A= 1.063. You can assume that the gas
phase is an ideal mixture of ideal gases. What is the pressure and the composition of the azeotrope?
