Pressure Unit
Raoult's Law Formula
P_i = x_i × P°_i
Partial vapor pressure of component i
P_total = Σ(x_i × P°_i)
Total vapor pressure of solution
P_i: Partial vapor pressure of component i
x_i: Mole fraction of component i
P°_i: Vapor pressure of pure component i
Common Applications
Distillation
Predicting boiling points and separation efficiency in fractional distillation processes.
Solution Chemistry
Understanding colligative properties like boiling point elevation and freezing point depression.
Phase Equilibria
Calculating vapor-liquid equilibrium in ideal and near-ideal mixtures.
Important Note
Raoult's Law applies to ideal solutions. Deviations may occur in non-ideal mixtures due to intermolecular interactions. Real solutions may show positive or negative deviations from Raoult's Law depending on the strength of molecular interactions between components.
