Consider a mixture of gas molecule of types $A, B$ and $C$ having masses $m_{A} < m_{B} < m_{C} .$ The ratio of their root mean square speeds at normal temperature and pressure is:

Options:

Answer:

Solution:

$V_{rms} = \sqrt{\frac{3 R T}{M}}$
$m_{A} < m_{B} < m_{C}$
$\Rightarrow V_{A} > V_{B} > V_{C}$
$\Rightarrow \frac{1}{V_{A}} < \frac{1}{V_{B}} < \frac{1}{V_{C}}$
