Does hydrogen gas have a low rate of diffusion?
No, it is the lightest gas of the universe so has the highest rate of diffusion.
Why diffusion is maximum in gases?
Diffusion is maximum in gases because gas molecules are not closely packed together like in liquids or solids. This allows gas molecules to move more freely and quickly, leading to faster diffusion rates compared to liquids or solids. Additionally, gas molecules have higher kinetic energy, allowing them to move more rapidly and spread out more easily through a medium.
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.
What gases diffuses fastest under the same conditions of temperature and pressure?
because the molecules in a gas have no fixed position relative to one another and can move freely.
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 rate of diffusion in liquid is slower than in gases?
The rate of diffusion in liquids is slower than in gases because the particles in liquids are closer together and have stronger intermolecular forces, which hinders their movement compared to gas particles. This results in a slower diffusion rate in liquids.
What gas has the slowest rate of diffusion?
Gas molecule always move. The movement is called Brownian Motion, a random behaviour of molecule and atom in fluid state. These little motion enhance diffusion even without any additional driving force. Gas had less interaction force than liquid and so the speed of motion is a lot greater and so higher diffusivity.
Does hydrogen gas have a low rate of diffusion?
No, it is the lightest gas of the universe so has the highest rate of diffusion.
Is diffuses faster air or oxygen gas?
Oxygen gas diffuses faster than air because air is a mixture of gases that includes nitrogen, oxygen, carbon dioxide, and other gases, which can affect the overall diffusion rate. Oxygen, being a pure gas, has a higher diffusion rate compared to air.
Why does hydrogen gas diffuses faster than other gases?
The rate of diffusion of a gas is inversely related to the molecular weight of that gas. The lighter the gas, the faster it diffuses. Hydrogen is the lightest of all gases having a molecular weight of only 2. Thus it diffuses faster than all others.
What results would you expect if two models were compared in a diffusion test?
The rate of diffusion would be faster for the right cylinder.
Does diffusion happen best in liquids?
The rate of diffusion is fastest is gasses, but as we can't see the gases ,it can be seen it liquids, but in liquids the rate of diffusion is comparatively slower than gasses and it can be easily observed....

Why is the rate of diffusion of gases more rapid than that of liquids?
Gases diffuse faster than liquids because the intermolecular forces holding gases together are significantly weaker than those holding liquids together. This allows the molecules of the gas to move faster than those of a liquid.
What is the ratio of the rates of diffusion of hydrogen gas to ethane gas C2H6?
According to Graham's Law of Effusion, the rate of diffusion of a gas is inversely related to the square root of the molar mass. Thus, smaller (lighter) gases diffuse faster than larger, heavier gases. Molar mass of H2 = 2 and molar mass of C2H6 = 30. Sqrt 2 = 1.41 and sqrt 30 = 5.48, so the ratio is 5.48/1.41 = 3.88 or H2 will diffuse almost 4x faster (3.88x) than ethane. The ratio of H2/C2H6 would be the inverse, or 1.41/5.48 = 0.257, meaning that the rate of diffusion of ethane is about 26% that of hydrogen.
