Points to Remember
Graham’s Law of diffusion can also be stated as the rate of diffusion of gases is inversely proportional to the square root of their molecular masses.
Application of Graham’s Law of Diffusion:
- To determine the vapour density and molecular mass of a gas.
- To separate gases from their mixture.
- To separate the isotopes of same element.
