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.
Why hydrogen diffuses four times more than helium?
Hydrogen has a smaller atomic size and lower atomic mass compared to helium, allowing it to move faster and diffuse more rapidly. Additionally, hydrogen has a higher kinetic energy at a given temperature, which also contributes to its increased diffusion rate.
What is the molar mass of a gas that takes three times longer to effuse than helium?
You want Graham's law of effusion, which is:rate1/rate2 = square root of (M2/M1). You're trying to find M2, because you know that M1 = 4 and rate 1 = 1 for He. I just set rate1 to 1 because it's a question that involves relative amounts). Rate 2 = 3xrate1 = 3. Plug in and solve.After a little rearranging, you should get:3^2 = M2 /4, or 36 g/mole.Something like O2 would fit the bill.ahaha, im smart !!
Which pair of gas has same rate of diffusion at STP?
Hydrogen and helium have the same rate of diffusion at standard temperature and pressure (STP) due to their similar molecular weights and sizes.
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.
How does the rate of effusion of sulfur dioxide compare to that of helium?
The rate of effusion of sulfur dioxide is slower compared to that of helium. This is because sulfur dioxide is a heavier molecule than helium, so it moves through a small opening at a slower pace. Helium, being a lighter gas, effuses faster due to its lower molecular weight.
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)?

How does the rate of effusion of sulfur dioxdeSO2 compare to that of heluim (He)?
The rate of effusion of helium (He) is typically faster than that of sulfur dioxide (SO2) because helium has a lower molar mass, which makes its gas particles move faster on average. This means that helium molecules can escape through a small opening more rapidly than sulfur dioxide molecules.
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.
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.
What is rate of effusion of Argon?
The rate of effusion of argon is determined by its molecular weight and temperature. Argon, being a monoatomic gas, has a higher rate of effusion compared to heavier gases like nitrogen and oxygen at the same temperature. The exact rate of effusion can be calculated using Graham's law of effusion.
How can one determine the effusion rate of a substance"?
To determine the effusion rate of a substance, one can measure the time it takes for the substance to pass through a small opening or pore. By comparing this time to the effusion rate of a known substance under the same conditions, the effusion rate of the substance in question can be calculated.
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.
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.
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.
What is the relationship between the rate of effusion of a gas and its molecular weight, according to the statement that "the rate of effusion of a gas is proportional to" something?
According to Graham's law of effusion, the rate of effusion of a gas is inversely proportional to the square root of its molecular weight. This means that lighter gases will effuse faster than heavier gases.
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.
