O Flash Distillation (or Single-Stage Contact) A mixture of 60 mole % n-heptane and 40 mole % toluene is vaporized at 101.325 kPa (absolute) until 40 moles of vapor and 60 moles of liquid in equilibrium with each other are produced. This occurs in a single- stage system and the vapor and liquid are kept in contact until equilibrium is achieved. Calculate the composition of the vapor and liquid. Note: Assume the system exhibits ideal behavior (which it mostly does), e.g. Raoult's Law applies and an Antoine's Vapor Pressure correlation is a sufficiently accurate model of component vapor pressure.
