(a) When chlorine atoms react with atmospheric ozone,what are the products of the reaction? (b) Based on averagebond enthalpies, would you expect a photon capable ofdissociating a C—Cl bond to have sufficient energy to dissociatea C—Br bond? (c) Would you expect the substanceCFBr3 to accelerate depletion of the ozone layer?
It is often said that water vapour amplifies the Earth’s greenhouse effect. Indicate one way that an increased atmospheric concentration water vapour can increase the greenhouse effect and one way that it can decrease the greenhouse effect.

- Chlorine atoms contribute to the destruction of the Earths ozone layer by the following sequence of reactions: Cl + O3 ClO + O2 ClO + O Cl + O2 where the O atoms in the second step come from the decomposition of ozone by sunlight: O3(g) O(g) + O2(g) What is the net equation on summing these three equations? Why does this lead to ozone loss in the stratosphere? What is the role played by Cl in this sequence of reactions?

- Which of the following is not true? 1. When conditions are NOX-limited, the excess of VOCs in the atmosphere quickly oxidize available NO to NO2. 2. Reducing the concentration of NOX may lead to an increase in ozone formation when conditions are VOC- limited. 3. Smog episodes are not initiated during nighttime hours, because the hydroxyl radicals necessary to initiate the reactions are formed due to photodecomposition reactions. 4. Photochemical smog never occurs in areas without significant vehicle traffic and power plant emissions. 4. Metropolitan areas surrounded by wooded areas need to focus their smog reduction on limiting NOX concentrations due to the VOCs produced by surrounding trees.arrow_forwardThe tropospheric processes discussed in this chapter cannot be considered as independent reactions.
