Chapter 10, Problem 10.102SP

Interpretation Introduction

Interpretation:

Difference between effusion and diffusion should be given.

Concept introduction:

Graham’s law suggests that effusion rate of gases varies inversely with square root of molecular weight. Mathematically it can also be stated as,

$\frac{{\text{Rate}}_{\text{1}}}{{\text{Rate}}_{\text{2}}}=\sqrt{\frac{M_{\text{2}}}{M_{\text{1}}}}$

Where,

• ${\text{M}}_{\text{2}}$ represents the molar mass of second gas.
• ${\text{M}}_{\text{1}}$ denotes the molar mass of first gas.
• ${\text{Rate}}_{\text{1}}$ denotes rate of effusion of first gas.
• ${\text{Rate}}_{\text{2}}$ denotes rate of effusion of second gas.
