All particles of an ideal gas have the same KE. If a gas particle has a small mass, it takes less energy to move a specified distance when compared to a gas particle with a larger mass.
KE = mu2(squared) / 2
KE = average kinetic energy
m = mass of the particle
u = average velocity of the particle
Also Graham's Law"
Rate1 / Rate2 = square root of (Mass2 / Mass 1)

Which will diffuse faster AsH3 or HCN?
HCN will diffuse faster due to its lower molecular weight.
Why nitrogen diffuses faster in high temperature?
Higher temperatures mean more heat energy which translates into more kinetic energy of the molecules of nitrogen gas. This greater kinetic energy allows the molecules to diffuse faster than at a lower temperature and lower kinetic energy.
How can you prove that gases diffuse in air?
Because, Nothing can be concentrated in air.. Everything travels from an area of high pressure to lower pressure.
Do elements at the bottom of a group have lower atomic masses than those at the top?
No its from top to bottom
Is the higher the millisecond faster than a lower millisecond?
No.
Which will diffuse faster AsH3 or HCN?
HCN will diffuse faster due to its lower molecular weight.
Which gas will diffuse faster methane or carbon dioxide?
Helium diffuses twice faster as Methane does.
Which gas diffuse faster CO2 or sulfur dioxide why?
CO2 diffuses faster because it has a lower molecular mass.
Would a substance of high molecular weight diffuse faster than a substance of lower molecular weight?
yes, a substance of high molecular weight will diffuse faster than a substance of lower molecular weight since the molecules will absorb the liquid and easily soak the other molecules,all round,hence diffuse faster
Do ionic compounds have a irregular structure?
Propanone has a lower boiling point and evaporates faster.
Which would diffuse faster ammonia or hydrochloric acid?
Ammonia would. The lower the molecular mass the faster it diffuses,. Ammonia (NH3) has a mass of about 17 AMU while hydrochloric acid about 36.5
Why nitrogen diffuses faster in high temperature?
Higher temperatures mean more heat energy which translates into more kinetic energy of the molecules of nitrogen gas. This greater kinetic energy allows the molecules to diffuse faster than at a lower temperature and lower kinetic energy.
Would you expect the particles in chlorine gas to diffuse faster or slower than the particles in argon 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. Chlorine molecules weigh 71 units. So we would expect nitrogen to diffuse more quickly than chlorine.
What has a higher density lower or higher masses?
i do not no
why does paraffin wax melt faster than sodium chloride?
An organic compound has a lower melting point that an inorganic ionic salt; the bonds in ionic compounds are stronger.
Compared with ionic compounds solid molecular compounds generally?
a lower melting point
Why does a less dense gas diffuse faster than a more dense gas?
Kinetic interpretation of gas pressureThe kinetic molecular theory makes it easy to see why a gas should exert a pressure on the walls of a container. Any surface in contact with the gas is constantly bombarded by the molecules. At each collision, a molecule moving with momentum mv strikes the surface. Since the collisions are elastic, the molecule bounces back with the same velocity in the opposite direction. This change in velocity ΔV is equivalent to an acceleration a; according to Newton's second law, a force f = ma is thus exerted on the surface of area A exerting a pressure P = f/A.
