A mixture of 30 mol% ethanol and 70 mol% water is charged to an equi- ibrium flash tank, which is at 1 atm pressure. To what temperature chould the tank be adjusted to produce exactly 50% vapor and 50% liq- nid? What are the liquid and vapor phase compositions at this tempera- ure? Calculate the fractional recoveries of ethanol and water, and the eparation factor,
