ints] liquid mixture of 65-mol-% n- heptane (1) and 35-mol-% ethyl ethanoate (2) is in equilibrium with its vapor at 70 C. For the liquid phase at this temperature, you are given G" /RT =1.2**. The pure component saturation pressures at 70 " Caregiven pat = 73.14 kPa and * = 32.27 kPa. Assuming the modified Raoule's law (yp = x2.pro) to be applicable for system: 1) Verify that in y, = 1.2x; and In y = 1.2x? (verify just one of them) 2) Sketch a typical P-X1-y, for an azeotropic binary system at a certain temperature, and show (10) 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?) 1151 4) If the above system forms an azeotrope at 70 C, find x, y, and p 1151
