The reduction of nitrogen monoxide is described by the following chemical equation: 2h2 (g) +2no (g) 2h20 ()n2 (g suppose a two-step mechanism is proposed for this reaction, beginning with this elementary reaction: h2 g+2no(g)- n20 (g)+h20(g) suppose also that the second step of the mechanism should be bimolecular suggest a reasonable second step. that is, write the balanced chemical equation of a bimolecular elementary reaction that would complete the proposed mechanism
