The particle models shown above represent a proposed two-step mechanism for the destruction of ozone (03) in the upper atmosphere. Based on the proposed mechanism, what is the balanced chemical equation for the overall reaction? O 03(9) + Cl(g) → 02(9) + CIO(9) O 203(9) + 2C1(9) → 202(g) + 2CIO(g) O 03(9) + Cl(g) + ClO(g) 202(9) + Cl2(g) O 203(9) 302(g)

Ozone in the troposphere is formed by the following steps: NO2 → NO + O (1) 0 + 02 → 03 (2) The first step is initiated by the absorption of visible light (NO, is a brown gas). Calculate the longest wavelength required for step 1 at 25°C. nm
Chapter #3, Question #6: A catalyst may be defined as a substance that enhances the rate of a chemical reaction without being consumed in the process. By this definition, a catalyst would have an infinite lifetime. The ozone decomposition catalysts, however, have finite lifetimes. What are possible sinks for removal of the stratospheric catalysts, NO and ∙Cl?
