Chapter 10, Problem 10.17P

Interpretation Introduction

Interpretation:

The gas between oxygen and krypton that diffuses faster needs to be determined.

Concept introduction:

The intermolecular distance between the particles of gases is very large thus, they are randomly distributed and have space between them. Due to the space, the particles of gases are in random motion and diffusion of gases takes place from one place to another. The rate of diffusion is proportional to the kinetic energy of the gaseous particles.

According to Graham’s law of diffusion of gases:

$\frac{{\text{rate}}_{\text{1}}}{{\text{rate}}_{\text{2}}}\text{=}\frac{{\text{molar mass}}_{\text{2}}}{{\text{molar mass}}_{\text{1}}}$

Here, 1 and 2 are two different gases.
