Question

Why does nitrogen gas diffuse faster than chlorine gas?

Answer 1

It is obvious that the smaller the molecular weight, the greater is the speed of the molecules of gas.

As chlorine gas has a molar weight of Cl2=71g and nitrogen has a molar weight of N2 28g , it is expected that the molecules of chlorine will diffuse slower compared to the molecules of nitrogen.

Answer 2

Answer:

This is such an interesting question.

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.
