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. WebMar 16, 2024 · Graham's law of diffusion, also known as Graham's law of effusion, states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its molecular weight. According to Graham's law, lighter gases diffuse or effuse quickly than heavier gases at the same temperature and pressure. WebHe 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.
