Chapter 10.6, Problem 2CP

Interpretation Introduction

Interpretation:

The gas that effuses faster and the time taken to effuse is to be calculated.

Concept introduction:

The root mean square velocity for the two molecules in two different gases at the same temperature can be calculated as

$\frac{u_{\text{rms}}(1)}{u_{\text{rms}}(2)}=\frac{\sqrt{M_2}}{\sqrt{M_1}}$

Here, $u_{\text{rms}}(1)$ represents the root mean square velocity of the one gas, $M_1$ represents its molar mass, $u_{\text{rms}}(2)$ represents the root mean square velocity of the second gas, and $M_2$ represents its molar mass.
