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.
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 substance has the lowest re-absorption rate?
Urea
what are the gases diffuse at lowest rate?
gases with the higher molar mass
Which us city has the lowest annual humidity rate?
Las Vegas.
What is the rate of effusion of nitrogen compared to oxygen?
The rate of effusion for nitrogen is higher.
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 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.
How is the effusion rate of gas related to its molar mass?
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.
Increase in expected growth rate does what to required return rate?
An increase in a firm's expected growth rate would normally cause its required rate of return to
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)?
50000
Mortality of pleural effusion?
The mortality of pleural effusion depends on various factors such as underlying cause, patient's overall health, and timely treatment. In general, if pleural effusion is treated promptly and effectively, the mortality rate is low. However, severe or untreated cases can lead to complications such as respiratory failure and sepsis, which can increase mortality risk.
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.
Relationship between gas's molecular weight and speed of effusion?
Higher is the molecular mass lower is the rate of effusion, when mass increases by 4 times rate decreases to one half (Graham's law of diffusion).
How does the rate of effusion of sulfur dioxide compare to that of helium?
Sulfur dioxide diffuses at one-quarter the rate of helium
Which of these mortgage loans would have the lowest rate?
one year
