Question

The ratio of rates of diffusion of $S{O}_2,O_2$ and $C{H}_4$ is

• A. $1:\sqrt{2}:2$
• B. 1 : 2 : 4
• C. $2:\sqrt{2}:1$
• D. $1:2:\sqrt{2}$

Answer 1

Answer: (A)

$r_{S{o}_2}:r_{o_2}:r_{C{H}_4}=\frac{1}{\sqrt{M_{S{O}_2}}}:\frac{1}{\sqrt{M_{o_2}}}:\frac{1}{\sqrt{M_{C{H}_4}}}$
$=\frac{1}{\sqrt{64:32:16}}=\frac{1}{\sqrt{4:2:1}}$
$\frac{1}{2}:\frac{1}{\sqrt{2}}:\frac{1}{1};\frac{2}{2}:\frac{2}{\sqrt{2}}:\frac{2}{1};1:\sqrt{2}:2$
