Q. When r, P and M represent rate of diffusion, pressure and molecular mass, respectively, then the ratio of the rates of diffusion $(r_A/r_B)$ of two gases A and B, is given as:

AIEEEAIEEE 2011States of Matter

Solution:

$r \propto \frac{P}{\sqrt{M}}$
$\frac{r_{A}}{r_{B}}= \frac{P_{A}}{P_{B}} \sqrt{\frac{M_{B}}{M_{A}}}$
