Chapter 20, Problem 9RQ

What catalyst is effective in the destruction of atmospheric ozone, ${\text{O}}_3$ ?

To determine

The effective catalyst in the destruction of atmospheric ozone, ${\text{O}}_3$ .

Answer to Problem 9RQ

The chlorine atoms are an effective catalyst in the destruction of atmospheric ozone ${\text{O}}_3$ .

Explanation of Solution

The ozone molecule is a molecule made up of three oxygen atoms. The Earth’s outer layers are composed of an ozone molecule. More specifically, the stratosphere layer at the upper atmosphere and the troposphere at the lower atmosphere are composed of the ozone molecule. They make the protective covering of the Earth’s atmosphere.

The ozone molecule constituting three oxygen atoms are highly reactive in nature and can decompose with some radical species or atoms reaching the ozone layer. These radical species or atoms act as a catalyst in the process of decomposition or destruction of atmospheric ozone.

The chlorine atoms from the CFC’s are highly reactive and easily approach the ozone layer for the destruction process.

Conclusion:

Therefore, the chlorine atoms act as an effective catalyst in the process of the destruction of atmospheric ozone ${\text{O}}_3$ .
