The proposed steps for a catalyzed reaction
WebbThe mechanism of this reaction is believed to involve the following two elementary steps: 2 NO 2 → NO 3 + NO NO 3 → NO + O 2 Note that the intermediate species NO 3 has only a … WebbThe catalyst was separated by filtration under hot conditions after 20 min of reaction when yield was observed as 56.0 ± 0.4%. The reaction was continued without the catalyst for another 120 min. Observably, the yield slightly increased from 56.0 ± 0.4% to 57.6 ± 0.3%, which is an increase of 1.6% (see SI, Fig. S2).
