Explain why nitrogen gas diffuse faster than chlorine gas

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.

Nitrogen weights 28 units and chlorine is 71 units . In that case nitrogen will diffuse faster

the answer is the first option

just googled it m8. not that hard
