Raoult’s Law Formula
Raoult’s law equation mathematically is written as:
Psolution = ΧsolventP0solvent
where,
- Psolution is Vapour pressure of Solution
- Χsolvent is Mole Fraction of Solvent
- P0solvent is Vapour Pressure of Pure Solvent
Raoult’s Law
Raoult’s Law in chemistry relates partial pressures of volatile liquid components to their mole fractions in a liquid solution. It states that the partial pressure of each component in the solution is directly proportional to its mole fraction. Thus, it helps us to calculate the total vapour pressure of the solution. Based on Raoult’s law, liquid solutions are classified as Ideal Solutions and Non-Ideal Solutions.
In this article, we will discuss the definition of Raoult’s law, ideal and non-ideal solutions, Raoult’s law for non-volatile solutes and some solved numerical problems based on Raoult’s law.
