Assume water and n-octane are immiscible.
a) Since the liquids are immiscible, all liquid phases are pure. What is for a pure species?
b) Calculate the boiling point for water and n-octane at 1 bar.
c) Sketch a Txy diagram (with the x-axis as the mole fraction of water) for the binary mixture at 1 bar. Label the boiling points.
d) Calculate the temperature at which VLLE occurs. (Hint: at VLLE of immiscible liquids, a vapor mixture is in equilibrium with two pure liquids).
e) A system contains 80 mol% water. At what temperature does the first vapor bubble appear? What is the composition of the vapor bubble?
f) Which liquid (water or octane) boils off first? At what temperature does this liquid completely boil off?
g) At what temperature does the other liquid boil off?
