VLE for n-hexane and n-heptane at 1 atm are provided on the next two pages. Use them to answer the following questions.

If the feed is 0.50 mole fraction n-hexane, 100 kmol/h, with 70% vapor, what are the compositions, flowrates, and temperatures of the liquid and vapor products?

If the feed is 0.50 mole fraction n-hexane, 100 kmol/h, and the vapor mole fraction is 0.65, what are the liquid mole fraction and the liquid and vapor flowrates and temperatures?
