Chapter 20, Problem 20.75QP

(a)

Interpretation Introduction

Interpretation:

The concentration of $\text{OH}$ is so small compared to ${\text{O}}_{\text{3}}\text{and}{\text{H}}_{\text{2}}\text{O}$ in the troposphere this has to be explained.

(b)

Interpretation Introduction

Interpretation:

The property which makes $\text{OH}$ a strong oxidising agent has to be predicted.

(c)

Interpretation Introduction

Interpretation:

An equation for the reaction of $\text{OH}$ with ${\text{NO}}_{\text{2}}$ which contributes to acid rain has to be written.

(d)

Interpretation Introduction

Interpretation:

An equation for the oxidation of ${\text{SO}}_{\text{2}}\text{to}{\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ by the $\text{OH}$ radical has to be written.
