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 molecule during these reactions. (10[1])Preventing the backflow of one of these reactions in stacks can be accomplished with sweep gas. Gaseous products of these reactions react with nitrogen oxides and light to generate ozone. In these reactions, gases pass over platinum and rhodium to limit the release of VOCs. (-5[1])Those catalytic converters following these (-5[1])reactions (10[1])reduce the formation of photochemical smog in cities. (10[1])For 10 points, name these reactions in which a chemical reacts with an oxidant (10[1])like oxygen (10[2])to release heat (10[1])and light. ■END■ (10[3])
