Question

With an activity show that lighter gases diffuse faster than heavier gases describe an expression between their rates and molecular masses

Answer 1

Molecular weight will affect the rate ofdiffusion. All other things being constant, lighter weight molecules will move faster or diffuse faster that heavier molecules. ... The rate of diffusion is inversely proportional to the square root of molar mass.

if we take HCl &NH3 both in a open flask we find that ammonia which is lighter than HCl diffuses faster than HCl..

This activity shows lighter gases diffuse faster than heavier gases...
