A process related to diffusion is effusion, the process by which a gas escapes from a container into a vacuum through a small hole. The rate of effusion is also related to root mean square velocity-heavier molecules effuse more slowly than lighter ones. The rate of effusion-the amount of gas that effused in a given time- is inversely proportional to the square root of the molar mass of the gas.

What does the diffusion of gases tell us about their particle size?
The larger the particle size, the slower it will diffuse. This is given by Graham's Law of effusion which states that the rate of effusion is inversely related to the square root of the molar mass of the gas.
How can you compare the rates of effusion of two gases in a mixture?
The rate of effusion of two gases in a mixture is inversely proportional to the square roots of their molar masses.
What is the rate of effusion of nitrogen compared to oxygen?
The rate of effusion for nitrogen is higher.
What is the ratio of the rates of diffusion of hydrogen gas to ethane gas C2H6?
According to Graham's Law of Effusion, the rate of diffusion of a gas is inversely related to the square root of the molar mass. Thus, smaller (lighter) gases diffuse faster than larger, heavier gases. Molar mass of H2 = 2 and molar mass of C2H6 = 30. Sqrt 2 = 1.41 and sqrt 30 = 5.48, so the ratio is 5.48/1.41 = 3.88 or H2 will diffuse almost 4x faster (3.88x) than ethane. The ratio of H2/C2H6 would be the inverse, or 1.41/5.48 = 0.257, meaning that the rate of diffusion of ethane is about 26% that of hydrogen.
How does the rate of effusion of sulfur dioxide compare to that of helium?
Sulfur dioxide diffuses at one-quarter the rate of helium

What is the rate of effusion of a gas is inversely proportional to the square root of its molar mass?
Graham's law of effusion.
What is Graham's law of effusion?
Graham's law of effusion states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. In other words, lighter gases effuse or diffuse at a faster rate than heavier gases under the same conditions.
Which stateWhich statement about the effusion rates of nitrogen and oxygen is truement about the effusion rates of nitrogen and oxygen is true?
The rate of effusion is inversely related to the square root of the molar mass. Or stated another way, the larger or heavier the gas, the slower the effusion rate. Nitrogen gas (N2) has a molar mass of 28 g/mole and oxygen gas (O2) has a molar mass of 32 g/mole. Nitrogen will diffuse faster. rate N2/rate O2 = sqrt 32/sqrt 28 = 5.66/5.29 = 1.07. So, N2 effuses 1.07x faster than O2, or 7% faster. For more information on this, look up Graham's Law of Effusion.

What are the variables involve in Graham's law?
The variables involved in Graham's law are the molar mass of the gas particles and the rate of diffusion or effusion of the gas. The rate of diffusion or effusion is inversely proportional to the square root of the molar mass of the gas particles.

Why gases have higher chance of leaking through holes?
Gas leaking through a small hole in its container is called effusion. The rate of effusion depends upon molar mass. The smaller the molar mass, the more quickly a gas will effuse out. Given these gases: He, Ar, CO2, helium will effuse out the fastest because its molar mass is only 4 (compared to 40 for argon and 44 for carbon dioxide.)
How can you compare the rates of effusion of two gases in a mixture?
The rate of effusion of two gases in a mixture is inversely proportional to the square roots of their molar masses.
