Which Gas Has Highest Diffusion Rate?

by

Which Gas Has Highest Diffusion Rate? As per Graham’s law, the rate of effusion or diffusion is inversely proportional to the square root of its molecular weight. Consequently, the gas with the least molecular weight effuses the fastest hence, helium gas has a higher rate of diffusion compared to nitrogen or oxygen. Why do gases

In Which State Of Matter Is There The Greatest Molecular Motion? Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. What has the greatest molecular motion? So, gases molecules having weak intermolecular attraction move randomly and show highest molecular motion as compared to solids
