104 SIMPLE MODELS FOR VAPOR/LIQUID EQUILIBRIUM

The two major assumptions required to reduce VLE calculations to Raoult\'s law are: The vapor phase is an ideal gas The liquid phase is an ideal solution (Sec 11 8) The first assumption means that Raoult\'s law can apply only for low to moderate pressures

Lecture 20 Chapter 10 sections 4-7

We can use the experimental result that (for similar liquids) the mole fraction of the substance A in the mixture is approximately pA/pA * or the ratio of the partial vapor pressures of each component in a mixture to its vapor pressure as a pure liquid: pA = XApA * (Raoult’s law) 200 Binary mixture obeying Raoult’s Law (Fig 10 3 from MT) 100

Does Raoult's law underestimate Va-Por pressure?
At low temperatures (near ambi-ent), Raoult’s law appears to slightly underestimate the va-por pressures of these mixtures.
What is a ideal solution based on Raoult's law?
Ideal solutions are mixtures that obey Raoult’s law through the entire range of compositions of the mixture. The vapor pressure of the mixture, Pvap, is equal to the sum of xi, the components’ mole fractions, times Pi°, their re-spective pure component vapor pressures.
How does Raoult's law apply to sublimation?
The vapor pressure of the mixture, Pvap, is equal to the sum of xi, the components’ mole fractions, times Pi°, their re-spective pure component vapor pressures. While commonly applied to liquid mixtures, Raoult’s law is also applied to solid mixtures undergoing sublimation.
How does Raoult's law work?
At equilibrium, the rate at which the solid or liquid evaporates is equal to the rate that the gas is condensing back to its original form. All solids and liquids have a vapor pressure, and this pressure is constant regardless of how much of the substance is present. Raoult's Law only works for ideal solutions.
