Extracted text: I. NONIDEAL SOLUTIONS Partial and total vapor pressures for methanol (Component B) and water (Component C) solution at 40°C is given in the Figure 1 below. a) Determine the vapor pressures of pure methanol and water and show on the figure. b) Show the partial pressure of methanol (Pmeth), partial pressure of water (Pwat), and total pressure (Ptot) on the related curve of the figure. c) Determine/calculate the partial and total pressures of the solution containing 0.4 mole fraction of liquid methanol. d) What are the vapor phase compositions of methanol and water in equilibrium with a solution containing 0.4 mole fraction of liquid methanol. e) Determine the Henry Constants of methanol and water for their dilute solutions. f) Calculate the activity _and activity coefficient_of Component B and Component C using Convention I and Convention II, when the solution has a mol fraction of (XB,liquid) 0.40. g) Make comments about the ideality of the solution.
