Which of the following is not true? O Catalytic converters facilitate both oxidation and reduction reactions simultaneously. O Carbon-based compounds (usually CO and hydrocarbons) are reduced in a catalytic converter to yield CO2 and H20. Reduction of the nitrogen in NO (to yield N2 and O2) is energetically favorable, but because the activation energy is high, the reaction must either be catalyzed or done at high temperatures to proceed at an appreciable rate. Catalytic converters that reduce the nitrogen in NO can also reduce the sulfur in SO2, resulting in production of the toxic gas H2S when sulfur is present in the fuel. CO and other incompletely oxidized forms of carbon are produced in greater quantities when gasoline is combusted with inadequate oxygen present.

The Nobel Prize in Chemistry was awarded in 1995 to Paul Crutzen, Mario Molina and Sherwood Rowland for research showing the chlorofluorcarbons (CFCs) were catalyzing the destruction of ozone in the stratosphere. The catalytic process can be described by a two step mechanism: (1) Cl + O3 --> ClO + O2 (slow) (2) ClO + O --> Cl + O2 (fast) Determine the overall reaction for this mechanism, and answer the following question: In this mechanism Cl acts as a(n) ______________ and ClO acts as a(n) ___________________. a. reagent, intermediate b. intermediate, catalyst c. catalyst, intermediate d. intermediate, product
Prof. Neiman and Prof. James were first to discovered in 1973 that chlorofluorocarbons (CFCs) were depleting the Earth’sozone layer when released into the atmosphere. Once they reach the stratosphere, Clis released from the CFCs molecules by interaction with UV light. Free Cl atoms areable to react with ozone in a catalytic cycle that converts O3into the more stable O2.It is estimated that a single Cl atom is able to react with∼100000 O3molecules.Although CFCs production was banned in 1996, there are still a substantial numberof motor vehicle air conditioners (MVACs) that use CFC-12 (CF2Cl2) as refrigerant.The average CFC-12 emission rate from operating MVACs has been estimated tobe 59.5 mg per hour per vehicle (Zhang et al.Environ.
