Question

a lighter gas diffuses more rapidly than a heavier gas why

Answer 1

The average kinetic energy of a gas particle is directly proportional to the temperature. An increase in temperature increases the speed in which the gas molecules move. All gases at a given temperature have the same average kinetic energy. Lighter gas molecules move faster than heavier molecules.

This lighter gas diffuses fast than heavier gas

Answer 2

hey
_____

the lighter gas particles has less density and they are having alot of spaces between and as we know that rate of diffusion depends on density as less the density it has , more is its diffusion rate

example - fluorine

heavier gas has more density and it has less diffusion rate

example - heavy water

hope helped
