Question

Calculate the ratio of the rate of diffusion of oxygen to the rate of diffusion of hydrogen at constant temperature and pressure.

Open in App

Solution

From Graham's law of diffusion
$r \propto \frac{1}{m}$
$\Rightarrow \frac{r_{O_{2}}}{r_{H_{2}}} = \sqrt{\frac{M_{H_{2}}}{M_{O_{2}}}}$
$\frac{r_{O_{2}}}{r_{H_{2}}} = \sqrt{\frac{2}{32}} = \frac{1}{4}$
