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 rapidly Why?
At any given temperature, small, light molecules (such as
H
2
, hydrogen gas
) diffuse faster than larger, more massive molecules (such as N
2
, nitrogen gas) because they are traveling faster, on the average (see heat; kinetic-molecular theory of gases).
How do you know which gas diffuses faster?
Diffusion is faster
at higher temperatures because the gas molecules have greater kinetic energy
. Effusion refers to the movement of gas particles through a small hole. Graham’s Law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.
Which gas diffuses faster than oxygen?
So, rate of diffusion of
hydrogen gas
is four times faster than oxygen gas.
Which matter diffuses the fastest?
The distance between the particles is more in
gases
than liquids which results in fast diffusion in gases than liquids. So the kinetic energy is more in gases particles so the diffusion in gases is more quicker than in liquid. So, the correct answer is option (B). Note: Diffusion is of two types.
Which two gases diffuse at the same rate?
Therefore the rate of diffusion of different gases is inversely proportional to the square root of their mass densities. r = (1÷√d) Since
CO2 and N2O
only have the same molar mass, there mass density will be same. Therefore CO2 and N2O will diffuse with same rate.
Which gas will diffuse at a faster rate CH4 or SO2?
∴
Methane gas
diffuses 2 times faster than SO2.
Which of gases diffuses faster among N2 O2 and CH4 Why?
Answer Expert Verified
The lighter a gas is, the faster it will tend to diffuse. The molecular weight of CH4 is 16, of N2 28 and of O2 32 respectively. Therefore
CH4 will diffuse
fast, and then will N2, and eventually O2 will be seen diffusing.
Do gas diffuse very fast?
Gases
diffuse very fast
because of the presence of large spaces between the gaseous particles and high kinetic energy of these molecules. They diffuse faster than the other states of matter.
What is gas diffusion?
Diffusion is the
process whereby gaseous atoms and molecules are transferred from regions of relatively high concentration to regions of relatively low concentration
. Effusion is a similar process in which gaseous species pass from a container to a vacuum through very small orifices.
What is an example of gas diffusion?
You can smell perfume
because it diffuses into the air and makes its way into your nose. 2. Cigarette smoke diffuses into the air. … In leaves, oxygen from the leaf cells diffuses out to the air.
Which gas has least rate of diffusion?
Explanation:
Carbon dioxide
has the greatest molecular mass and should be xpected to diffuse slowest. In terms of temperature carbon dioxide also has the lowest heat capacity of the 4 gases.
Which state of matter is diffusion The fastest?
Diffusion happens in all states of matter, from solid to liquid to gas. Diffusion occurs the quickest when matter is in
its gaseous state
. Diffusion is, quite simply, the movement of molecules from a very busy, or “concentrated,” area to one of less concentration.
Which state of matter is the fastest?
| A B | molecules move fastest in this phase plasma | molecules move faster than liquids in this state gas | molecules move the slowest in this state solid | molecules move around each other in this state liquid |
|---|
What is the fastest to slowest rate of diffusion?
Neon is
the fastest. Chlorine is the slowest.
Which of the following will diffuse more quickly?
H2 is
hydrogen gas
and it will diffuse the fastest as all other options contain metals either in solid state(Fe and Na) or liquid state(Hg). This is due to the fact that gases diffuse easily and faster than liquids and solids.
