WebJul 3, 2024 · Graham's law is a gas law which relates the rate of diffusion or effusion of a gas to its molar mass. Diffusion is the process of slowly mixing two gases together. Effusion is the process that occurs when a … WebCalculation: Graham’s law of diffusion The heavier the particle, the slower it traveled Graham worked out that the rate at which the particles spread out is inversely proportional to the square root of the molecular weight. We can write his law as a mathematical equation that should "fit" with the results you got from the simulation:
