Chapter 11, Problem 86QAP

Interpretation Introduction

Interpretation:

To determine the half-life of given reaction in years and identify whether this reaction contributes to the depletion of ozone layer.

Concept introduction:

Relation between rate constant and half-life for first order reaction:

$\begin{array}{l}\text{t}\frac{\text{1}}{\text{2}}\text{=}\frac{\text{0}\text{.693}}{\text{k}}\\ \text{where,}\\ \text{t}\frac{\text{1}}{\text{2}}\text{=}\text{Half-life}\\ \text{k}\text{=}\text{rate}\text{constant}\end{array}$
