The rate of effusion of a gaseous substance is inversely proportional to the square root of its molar mass. This relationship is referred to as Graham’s law, after the Scottish chemist Thomas Graham (1805–1869). The ratio of the effusion rates of two gases is the square root of the inverse ratio of their molar masses: \[ \color{red} \dfrac ...

Apr 29, 2024 · The rate of effusion calculator calculates the rate of diffusion or effusion of one gas into another based on the molar weights of the two gases. It can also give you the molar weight of a gas, based on its rate of diffusion.
Dec 9, 2019 · Graham's law expresses the relationship between the rate of effusion or diffusion of a gas and that gas's molar mass. Diffusion describes the spreading of a gas throughout a volume or second gas and effusion describes the movement of a gas through a tiny hole into an open chamber.
The diffusion rate depends on several factors: temperature; the mass of the atoms or molecules; the concentration gradient (the increase or decrease in concentration from one point to another); the amount of surface area available for diffusion; and the distance the gas particles must travel.
Jun 13, 2023 · We want to know the rate of effusion, which is how much gas moves through the hole per unit time. We assume that the gas particles don't bump into each other while they move through the hole (this means it's a narrow hole in a thin wall).
Graham’s law of effusion or prolixity is generally used to calculate the effusion or prolixity rate of a particular gas. It also helps to compare the effusion or prolixity rates of two different feasts.
This chemistry video tutorial provides a basic introduction into Graham's Law of Effusion. It explains how to use it to calculate the rate at which a gas ef...
