An equimolar liquid mixture of n-pentane and n-hexane at 80°c and 5 atm is fed into a flash evaporator at 100.0 mol/s. when the feed is exposed evaporator, a substantial amount is vapourized. the temperature in the tank is maintained at 65°c by adding heat. the vapour and liquid phases, which are in equilibrium with each to a reduced pressure in the as separate streams. the liquid product stream contains separated and discharged other, are 41 mole% petaie, determine: the system pressure in atmospheres, (10 points) b. the composition of the vapour stream, (10 points) c. the fraction of the propane that is vapourized. (10 points) a. pent
