Chapter 11, Problem 132DIA

Interpretation Introduction

Interpretation: The graph is to be studied and the given questions are to be answered.

Concept Introduction: At constant temperature and pressure, the volume of gas $\left(V\right)$ is directly proportional to the number of moles of gas $\left(n\right)$. It can be expressed as:

$V\propto n$

Nitrogen is oxidized in air to form ${\text{NO}}_{\text{2}}$.

${\text{NO}}_{\text{2}}$ and ${\text{O}}_{\text{3}}$ are examples of pollutant.

Usually, the inverse relation between concentration of ${\text{NO}}_{\text{2}}$ and ${\text{O}}_{\text{3}}$ is observed.
