WebFeb 1, 2024 · The ratio of the effusion rates of two gases is the square root of the inverse ratio of their molar masses: rate of effusion A rate of effusion B = √MB MA Figure 6.8.1 for ethylene oxide and helium. Helium ( M = 4.00 g/mol) effuses much more rapidly than ethylene oxide ( M = 44.0 g/mol). WebEffusion refers to the movement of gas particles through a small hole. Graham's Law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles. 2.9: Graham's Laws of Diffusion and Effusion is shared under a CC BY-NC-SA 4.0 license and was authored, remixed, and/or curated by LibreTexts.
