View Raoult's Law Graph Images. A french chemist, francois marte raoult gave the relationship between partial pressure and mole fraction of two components. Raoult's law states that the vapor pressure of a solvent above a solution is equal to the vapor pressure of the pure solvent at the same temperature scaled by the mole fraction of the solvent present.…
You have studied raoult's law you will be familiar with the graph of vapour pressure vs composition at constant temperature. Explains the shapes of the pxy and the txy diagrams for raoult's law. Raoult's law (/ˈrɑːuːlz/ law) is a law of physical chemistry, with implications in thermodynamics.
The raoult's law can be expressed mathematically as
Section 9.2.7 showed that if substance i has transfer equilibrium between a liquid and a gas phase. The escaping tendency of a solvent is measured by its vapor pressure. Raoult's law is a phenomenological law that assumes ideal behavior based on the simple microscopic assumption that intermolecular forces between unlike molecules are equal to those between similar. A french chemist, francois marte raoult gave the relationship between partial pressure and mole fraction of two components.
