Graham's law of diffusion

Vedclass · Answer

(B) The separation of a mixture of two gases based on their different rates of diffusion is governed by $Graham's \ law \ of \ diffusion$. According to this law,the rate of diffusion of a gas is inversely proportional to the square root of its molar mass $(Rate \ \propto \ \frac{1}{\sqrt{M}})$. By allowing the gas mixture to diffuse through a porous membrane,the lighter gas diffuses faster than the heavier gas,allowing for their separation.

Which technique is commonly used to separate a mixture of two gases based on their rates of diffusion?
