Question

Among the following, the correct statements are

• A. $C{H}_4$ gas diffuses $\sqrt{2}$ times more than $O_2$
• B. $He$ diffuse $\sqrt{2}$ times more than $O_2$
• C. $O_2$ diffuse 2 times more than $S{O}_2$
• D. $He$ gas diffuse 1.414 times than $H_2$ gas

Answer 1

The correct option is A $C{H}_4$ gas diffuses $\sqrt{2}$ times more than $O_2$

$\frac{r_1}{r_2}=\sqrt{\frac{M_1}{M_2}}$
Rate of diffusion of gas is inversely proportional to molecular weight of that gas.
