Rauolt's law

The vapour pressure of an ideal solution is dependent on the vapour pressure of each chemical component and the mole fraction of the component present in the solution.

 

Limitations

  • Intermolecular forces between the components in the solution should be similar to those intermolecular forces between individual molecules.

        If we have a solution of A and B 

        forces between A-A = B-B = A-B

 

  • The gaseous phase are assumed to be act as a ideal gas where we can use ideal gas law.
