Which of the following gases is the fastest to diffuse?

Correct answer: The rate of effusion for a gas is inversely proportional to the square-root of its molecular mass (Graham’s Law). The gas with the lowest molecular weight will effuse the fastest. The lightest, and therefore fastest, gas is helium.

Which gas diffuses faster oxygen or carbon dioxide?

In the lungs, whilst oxygen is smaller than carbon dioxide, the difference in solubility means that carbon dioxide diffuses roughly 20 times faster than oxygen.

Which gas will diffuse at the slowest rate?

Chlorine is the slowest.

Why nitrogen gas diffuses faster at higher temperature?

Answer: Since an increase in temperature represents an increase in the average molecular speed, diffusion occurs faster at higher temperatures.

Which gases would diffuse faster than carbon dioxide?

Molar mass CO2 is 44.01. Let carbon dioxide be gas # 2. Therefore, ammonia diffuses 1.61 faster than carbon dioxide. Empirical answer: the gas with the lesser molar mass will diffuse faster.

Which diffuses faster air or oxygen gas?

Oxygen is diffuses faster because the diffusion of gases is a unique property of them as the gaseous particles have high kinetic energy therefore they exhibit the random motion and move easily. Here oxygen gas has less molar mass compare to air, therefore, it will diffuse faster compared to air.

What is the rate of diffusion of ammonia?

1.46 times
The rate of diffusion of ammonia is 1.46 times faster than the rate of diffusion of hydrogen chloride. The molecular mass of helium and chlorine is 4.0 g and 71.0 g respectively. Chlorine will diffuse faster.

Which of the following will diffuse the slowest?

Solids diffuse the slowest as the particles in solids do not move from their fixed positions. Gases diffuse the fastest as the particles in gases move very quickly in all directions.

Which gas will diffuse faster HCL or nh3 Why?

The ammonia gas, having a lower molecular weight than the hydrogen chloride, will diffuse faster and travel a greater length of the tube. Consequently, the white ring of ammonium chloride will form much closer to hydrochloric acid end of the tube.

Why nitrogen gas diffuses faster than chlorine gas?

The rate of diffusion of a gas depends on the weight of the gas molecules. The heavier the molecules, the slower they move – the lighter the molecules, the faster they move. Nitrogen molecules weigh about 28 units. So we would expect nitrogen to diffuse more quickly than chlorine.

Which one of the following diffuses faster in air?

Gases diffuse the fastest as the particles in gases move very quickly in all directions.

Which of the gases diffuse faster among N2 O2 and CH4?

Solution : Methane gas diffuses faster than N2 and O2 because the molecular weight of Methane (16) is lesser than the molecular weights of N2(28) and O2(32).

Which of the following gases would tend to diffuse fastest?

The ammonia has the smallest relative molecular mass, 17, followed by nitrogen (28), oxygen (32) and carbon dioxide (44). Rate of diffusion depends on molecular mass, temperature and concentration gradient. In terms of molecular mass ammonia would tend to diffuse fastest.

Why does ammonia diffuse faster than other gases?

Ammonia (NH3) has the smallest molecular weight so it diffuses the fastest. Rate of diffusion is dependent on the molecular mass of the compound, the lighter the weight the higher the rate of diffusion, ammonia has the least molecular mass and as a result diffuses more than the rest.

Which gas effuses four times as fast as oxygen?

Hydrogen effuses four times as rapidly as oxygen. At a particular pressure and temperature, nitrogen gas effuses at the rate of 79 mL/s. According to Graham’s law of diffusion, the rate of diffusion or movement of gas is inversely proportional to the square root of it’s molecular weight.

Which gas effuses faster helium or he?

The lighter a gas is, the faster it will effuse; the heavier a gas is, the slower it will effuse. Of all the choices, helium (He) has the lowest molecular weight (atomic weight in this case), so it will have the highest rate of effusion. All this is further explained here.
