Grahams law of diffusion explained

WebIn1829, Thomas Graham, a Scottish Chemist formulated the Graham’s Law of the Diffusion and Effusion of Gases. According to this Law, the rate of Diffusion of different gases, at a constant temperature, is inversely proportional to the square root of its density.
