of mole fraction is shown below. Use Henry's law.as the reference state for species a and the Lewis/Randall rule for species b. Show all your work. (a) What is the Henry's law constant, Ha, for species a? (b) What is the activity coefficient for species a at x, =l0.4P At x, = 0.8? ( (c) Is the activity coefficient for species b at Xa0.4 greater than or less than 1? Explain. (d) Is the a-b interaction stronger than the pure species interactions? Explain. (e) Consider the vapor phase to be ideal. What is the vapor-phase mole fraction of a in equilibrium with 40% liquid a?
