Two liquids, A and B, show partial miscibility below 52.4 degrees Celsius. The critical temperature at the upper critical temperature is x=0.459, where x is the mole fraction of A. At 40° C the two solutions in equilibrium have x=0.22 and x=0.60, respectively, and at 42.5 degrees Celsius the more fractions are 0.24 and 0.28. Sketch the phase diagram. Describe the phase changes that occur when B is added to a fixed amount of A at (a) 48 degrees Celsius, (b) 52.4 degrees Celsius.
2. Sketching and interpreting a phase diagram. Two liquids, A and B, show partial miscibility below 52.4°C. The critical concentration at the upper critical temperature is x 0.459, where x is the mole fraction of A. At 400°C the two solutions in equilibrium have x 0.22 and x-0.60, respectively, and at 42.5°C the mole fractions are 0.24 and 0.48. Sketch the phase diagram. Describe the phase changes that oocur when B is added to a fixed amount of A at (a) 48°C, (b) 52.4°C
