Chapter 2, Problem 55Q
The effect a chemical substance has on the ozone layer is measured by a value called its ozone-depleting potential, ODP. This is a numerical scale that estimates the lifetime potential stratospheric ozone that could be destroyed by a given mass of the substance. All values are relative to CFC-11, which has an ODP defined as equal to 1.0. Use those facts to answer these questions.
- a. Name two factors that affect the ODP value of a compound, and explain the reason for each one.
- b. Most CFCs have ODP values ranging from 0.6 to 1.0. What range do you expect for HCFCs? Explain your reasoning.
- c. What ODP values do you expect for HFCs? Explain your reasoning.
