Which of the following is not true? Catalytic converters can facilitate both oxidation and reduction reactions simultaneously. 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. 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...
