Question
Chapter 11, Problem 54E
Interpretation Introduction
Interpretation:
The statement “Scientists suggest that the ozone layer is restored by chemically forming ozone and pumping it into the stratosphere” is to be explained.
Concept Introduction:
Ozone is an atmospheric gas that absorbs UV light from the Sun reaching the surface of the earth and thus protects the life on earth from excessive UV exposure. It is found in the stratosphere of earth and is composed of a high concentration of ozone gas. This layer is very beneficial for the atmosphere of earth.

- In Module #4, we discussed the role of chlorofluorocarbons (CFCs) in catalyzing the destruction of O3 in the stratosphere. One example of a CFC that is known to exasperate formation of the hole in the O3 layer is dichlorodifluoromethane (CF2Cl2). In the year 2000, this chemical reached its peak concentration of 2.2 x 10-11 M in the atmosphere. The destruction of CF2Cl2 can be approximated as a first-order process and the 1996 treaty on CFC emissions has eliminated its release into the atmosphere. Given that the rate constant for destruction of CF2Cl2 in the atmosphere is 0.009 yr-1, how long will it take for the concentration of CF2Cl2 to decline to 0.22 x 10-11 M?arrow_forwardGiven that the concentration of CH4 in the atmosphere is 1.8 ppm, calculate the total mass of this gas that is present in the atmosphere.
