A liquid mixture of 65mol% n-heptane (1) and 35 -mol-\% ethyl ethanoate (2) is in equilibrium with its vapor at 70C. For the liquid phase at this temperature, you are given GE/RT=1.2x1x2. The pure component saturation pressures at 70C are given P1sat=73.14kPa and P2sat=32.27kPa. Assuming the modified Raoult's law (yiP=xiiPisat) to be applicable for system: 1) Verify that ln1=1.2x22 and ln2=1.2x12 (verify just one of them) [10] 2) Sketch a typical Px1y1 for an azeotropic binary system at a certain temperature, and show on the sketch the regions of compressed liquid, superheated vapor and the region where the system has liquid and vapor in equilibrium. [10] 3) Do for the above system BUBBL P computation. What is the physical state of this system at pressures higher than this BUBBL P? (i.e., is it superheated gas, compressed liquid, or two-phase VLE?) [15] 4) If the above system forms an azeotrope at 70C, find x1az,y1az, and paz [15]
