Question 5: A phase diagram for two partially miscible liquids is given below. Note that the phase diagram is for a constant pressure p = 1.00 atm. vapor Temperature (0) 50 40 liquid P-1 liquid P-1 30 liquid P-2 0.4 0.8 0.6 wole fraction A a) The isopleth at T = 45.0C and mole fraction A = 0.644 (the horizontal line in the phase diagram). point c in located at mole fraction A = 0.618, and point d is located at mole fraction A = 0.886. In what proportions do both phases occur? The vapor pressure of pure A at T = 45.0C and mole fraction A = 0664 is PA* = 544.2 torr. Find the activity coefficient (YA) of A at this temperature in the liquid solution of A and B above. (1 atm = 760 torr) b) Question 5: A phase diagram for two partially miscible liquids is given below.
