Graham's law of effusion (also called Graham's law of diffusion) was formulated by Scottish physical chemist Thomas Graham in 1848. Graham found experimentally that the rate of effusion of a gas is inversely proportional to the square root of the molar mass of its particles. This formula is stated as: , WebThis formulation follows from Graham's observations and the facts that the rate of diffusion (or effusion) is directly proportional to the volume of gas diffused (or effused) in a given time and that the density of a gas is proportional to its molar mass. Note: Diffusion and effusion are distinct but related phenomena of molecular transport.
