Problem

According to Graham's law, at a given temperature the ratio of the rates of diffusion

\frac{r_A}{r_B}

of gases A and B are given by : (where

P

and

M

are pressures and molar masses of gases A and B respectively). a.

\left(\frac{P_A}{P_B}\right)\left(\frac{M_A}{M_B}\right)^{\frac{1}{2}}

\left(\frac{M_A}{M_B}\right)\left(\frac{P_A}{P_B}\right)^{\frac{1}{2}}

\left(\frac{P_A}{P_B}\right)\left(\frac{M_B}{M_A}\right)^{\frac{1}{2}}

\left(\frac{M_A}{M_B}\right)\left(\frac{P_B}{P_A}\right)^{\frac{1}{2}}
