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 else can I help you with?
Which molecule, based on its molar mass, would have a higher rate of effusion?
The molecule with a lower molar mass would have a higher rate of effusion.
Is the rate of effusion of a gas directly proportional to any specific factors?
Yes, the rate of effusion of a gas is directly proportional to the square root of its molar mass.
How does the rate of effusion of sulfur dioxide SO2 compare to that of helium (He) (Note the molar masses are SO2 64 gmol He 4.0 gmol.)?
The rate of effusion of a gas is inversely proportional to the square root of its molar mass. Helium has a molar mass of 4.0 g/mol, while sulfur dioxide has a molar mass of 64 g/mol. Therefore, the rate of effusion of SO2 will be √(4.0/64) = 1/4 times that of helium. In other words, sulfur dioxide will effuse more slowly than helium.
How can you compare the rates of effusion of two gases in a mixture?
The rate of effusion of gases is inversely proportional to the square root of their molar masses. By comparing the molar masses of the two gases, you can determine which gas effuses faster. The gas with the lower molar mass will effuse more quickly.
What is the rate of effusion of nitrogen compared to oxygen?
The rate of effusion of nitrogen is slightly lower than that of oxygen due to nitrogen being a slightly heavier molecule than oxygen. This is based on Graham's law, which states that the rate of effusion is inversely proportional to the square root of the molar mass of the gas.
Which molecule, based on its molar mass, would have a higher rate of effusion?
The molecule with a lower molar mass would have a higher rate of effusion.
The rate of effusion of Argon was measured to be 0.218mols at a certain temperature Calculate the rate of effusion of helium gas (Molar mass of Ar=40,Molar mass of Helium =4)?

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.
Is the rate of effusion of a gas directly proportional to any specific factors?
Yes, the rate of effusion of a gas is directly proportional to the square root of its molar mass.
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 does the diffusion of gases tell us about their particles?
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.

Which gases will have the greatest rate of effusion?
The slowest rate of effusion will be exhibited by the gas with the highest molar mass. For example, Xenon will diffuse at a slower rate than Helium, and chlorine will diffuse at a slower rate than fluorine.
