"WebGraham’s law states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its density or the square root of its molar mass at a given temperature and pressure. This means that lighter gas effuses or diffuses easily; whereas, heavier gas molecules take time to effuse or diffuse. " - Graham's law of diffusion of gases

9.4 Effusion and Diffusion of Gases – Chemistry

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. WebThe first to do the latter was Graham in 1831; he kept the pressure uniform by allowing the gas mixture to flow. The results of this work now appear in elementary textbooks as Graham’s law of diffusion.

Thomas Graham … 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:

WebFormula for Graham’s Law of Diffusion and Effusion. r ∝ 1/ (M)½. where, r = rate of diffusion or effusion. M = molar mass. The Molar Mass tells you the number of grams per mole of a compound. The units for molar mass is grams/mole. It indicates the number of atoms, ions, molecules, or formula units present in a particular chemical.
