  1. At 250C, the vapor pressure of pure pentane, n-C5H12 is 0.674 bar and that of pure hexane, n-C6H14 is 0.198 bar. Assuming these two compounds form an ideal solution:
  1. Prepare a pressure-composition (p vs mole fraction) diagram for this binary system.
  2. Calculate the partial pressure of each substance and the total pressure over the solution that has a mole fraction of pentane,  Xn-C5H12=0.35
  3. What is the composition of the vapor phase in equilibrium with the solution that has the same composition described in 6(b)?
