Chapter 11, Problem 30E

Interpretation Introduction

Interpretation:

The steps taken to phase out $\text{CFCs}$ are to be explained.

Concept Introduction:

$\text{CFCs}$ are chlorofluorocarbons, which are chemically inert.

$\text{CFCs}$ are responsible for the depletion of the ozone layer in the stratosphere.

The UV light in the stratosphere decomposes the $\text{CFCs}$ to chlorine atoms. The chlorine atom destroys ozone molecules in the stratosphere, causing depletion of ozone.
