Question

What is Graham’s Law of Diffusion?

Answer

Graham's Law of Diffusion is: The rate of diffusion of a gas through a porous partition is inversely proportional to the square root of its density. On the basis of kinetic theory of gases, the rate of diffusion through a fine hole will be proportional to the average or root mean square velocity, i.e., Rate of diffusion of one gas/Rate of diffusion of other gas
