This class of reactions produces a family of toxic compounds that have two benzene rings connected by two oxygen atoms at the para positions, the dioxin family. The Zeldovich mechanism explains the formation of a type of nitrogen-containing (-5[1])molecule during these reactions. Preventing the backflow of one of these reactions in stacks can be accomplished with sweep gas. (-5[1])Gaseous products of these reactions react with nitrogen oxides and light to generate ozone. (10[1])In these reactions, gases pass over platinum and rhodium to limit the release of VOCs. Those catalytic (-5[1])converters following these reactions reduce the formation of photochemical smog in cities. For 10 points, name these reactions in which a chemical reacts with an oxidant like oxygen to release heat and light. ■END■ (10[3])
