Chapter 11, Problem 11.87PAE

Interpretation Introduction

Interpretation:

The reason for presence of low concentration of ozone in photochemical smog should be identified.

Concept introduction:

The nascent oxygen reacts with the molecular oxygen to produce ozone gas as follows:

$\text{O }+{\text{ O}}_{\text{2}}+\text{ M} \to {\text{O}}_{\text{3}}+\text{ M}$

When these oxides of nitrogen produced from coal reacts with the presence of sunlight or UV reacts in the atmosphere results in the formation of photochemical smog which appears as brown gas.
