Chapter 19, Problem 19.67E

Interpretation Introduction

Interpretation:

The total distance travelled by the ammonia molecule in $1\text{minute}$ is to be calculated.

Concept introduction:

The expression for the average velocity of the molecules is calculated by integrating the product of probability function $G\left(v\right)$ and velocity $\left(v\right)$ with respect to $v$.

The average velocity of gas molecules is given by,

$\overline{v}=\sqrt{\frac{8RT}{\pi M}}$

Where,

• $R$ is the gas constant.

• $T$ is the temperature.

• $M$ is the molar mass of the gas.
