Graham's law of diffusion formula
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: , WebIn Thomas Graham. He developed “Graham’s law” of the diffusion rate of gases and also found that the relative rates of the effusion of gases are comparable to the diffusion rates. From examining the diffusion of one …
