Chapter 19, Problem 19.42E

Interpretation Introduction

Interpretation:

The variable(s) on which the average collision frequency depends on is to be predicted.

Concept introduction:

The average collision frequency is given by the formula,

$z=\frac{4\pi \rho d^2\sqrt{kT}}{\sqrt{\pi m}}$

Where,

• $\rho$ is the density.

• $T$ is the temperature.

• $m$ is the mass of an atom.

• $d$ is the collision diameter.

• $k$ is the Boltzmann constant
