What is the relationship between molecular weight and rate of diffusion?

Answer 1

Luna Chen

#U_(rms)=sqrt((3RT)/(MM))#

The rate of diffusion (#U_(rms)#) is given by:

#U_(rms)=sqrt((3RT)/(MM))#

where MM stands for the gas's molar mass.

Thus, when #MM# increases, the diffusion rate will decrease.

The rate of diffusion is inversely proportional to the molecular weight of a substance. This means that as the molecular weight increases, the rate of diffusion decreases. Conversely, as the molecular weight decreases, the rate of diffusion increases.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
