Avapor mixture of n-butane (b) and n-hexane (h) contains 50.0 mole% butane at 120 °c and 1 atm. a stream of this mixture flowing at a rate of 150.0 l/s is cooled and compressed, causing some but not all of the vapor to condense. (treat this process as a single-unit operation.) liquid and vapor product streams emerge from the process in equilibrium at t (°c) and 1100 mmhg. the vapor product contains 60.0 mole% butane. determine: a)the required final temperature (t) b)the composition of the liquid product (component mole fractions) c)the molar flow rates of the liquid and vapor products.
