7.) (15pts) Consider the two-component liquid-vapor phase diagram shown where pressure is held constant (Making the phase rule F=CP+1 ): f. Identify a region where F=1, label this F1 B. Identify a region where F=2, label this F2 h. Mark the boiling point of pure B, label this Ta. i. Draw an isopleth that crosses through a both a region of complete liquid miscibility and one of partial miscibility. Label this line, a. Indicate the total mole fraction of B for your isopleth. j. Find the points on your isopleth where T=225K and T=350K. Label these a1 and a2. If these points consist of more than one phase, identify the mole fraction of B in each phase and the relative amounts of each phase. k. Does this mixture represent positive or negative deviations from ideal solution behavior? Explain how you know
