Explanation: 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
.
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.
What is the fastest diffusion?
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).
Which gas diffuses faster among N2 O2 CH4 and why?
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 diffuses the fastest O 2 CH 4 CO 2 Cl 2 CH 4 O 2 CO 2 Cl 2?
The
methane gas
has lowest molar mass that is of 16 amu which means it will get diffuse fastest from the other enlisted gases.
Which diffuses faster liquid or gas?
Gases diffuse faster than liquids
. This is because the particles of gases are much farther apart from one another as compared to the solids and liquids. Also, the force of attraction between the particles is negligible, hence particles of a gas move freely in all the directions.
What is the slowest diffusing gas?
Chlorine
is the slowest. We must assume that all these gases are at the same temperature.
Which type of diffusion is very very slow?
The
diffusion of a solid in another solid
is a very slow process because the particles in solids can not move from their positions. the particles can show a little vibrations about their fixed position. due to lack of sufficient movements in particles of solids,the diffusion of solids in solids is a slow process.
What diffuses faster hydrogen or oxygen?
Hydrogen
effuses four times as rapidly as oxygen.
Why is diffusion fastest in liquid?
Diffusion in liquids
Diffusion can also happen in liquids. This is because
the particles in liquids can move around each other
, which means that eventually they are evenly mixed.
Which gas diffuses twice as fast as Sulphur dioxide?
Sulfur dioxide has a molecular weight of 64 and hence the square root is 8. Since its inversely proportional, to be able to diffuse twice as fast, the square root of the molecular weight should be 4, and hence the molecular weight would be 16. So the answer is
methane (CH4)
.
Which will diffuse faster ammonia or CO2?
Which states that the rate of effusion of a gas is inversely proportional to its density. This means, the heavier the gas is(in terms of its molecular weight), the slower it is. Hence,
ammonia is lighter
and from Grahams law of effusion, it then means that it will diffuse faster than CO2, which is heavier.
How many times method diffuses faster than Sulphur dioxide?
∴ Methane gas diffuses
2 times faster
than SO2.
Which gases will diffuse faster than CO2?
Which gas carbon dioxide or Sulphur dioxide would diffuse faster? According to grahams law of diffusion the rate of diffusion of gas is inversely is proportional to root of molecular mass of gas hence the molecular mass of
SO2
is more than molar mass of CO2 hence Co2 diffuse faster than SO2 .
Which gas diffuses faster ethene or methane?
Which gas diffuses faster and why?
A ethene Ethene molecules are heavier
and so move faster. … C methane Methane molecules are lighter and so move faster.
What is the rate of diffusion of a gas?
Graham’s law states that the rate of diffusion or of effusion of a gas is
inversely proportional to the square root of its molecular weight
.
