2. A liquid mixture of A and B displays an azeotrope at xA=0.7 at 384K and a pressure of 3.500 bar. The vapor pressures of A and B are Pvap(T)=exp[9.72800/(T56)] bar and A Pvap=exp[9.52900/(T58)] bar. Assume the binary obeys the van Laar model with B temperature-independent constants, and . (a) Determine values for the van Laar parameters and . (b) By hand, perform a bubble-point pressure calculation at xA=0.35 and T=384K, and report the bubble composition yA. (c) Using Python (or Excel, if you must), construct Pxy and xy diagrams for A/B mix-tures at 384K. Indicate the location of the azeotrope, and verify that it occurs at the (xA,P) reported in the problem statement above. (d) By hand, perform a bubble-point temperature calculation at xA=0.35 and P=3 bar. (Here, we are explicitly assuming and are not functions of temperature.) (e) Using Python (or Excel), construct T-x-y and xy diagrams for A/B mixtures at 3 bar
