State
This capstone carries one reaction from its experimentally determined rate law, through collision theory's activation-energy picture, to a proposed mechanism and its catalyzed pathway, showing that a rate law, a mechanism, and a catalyst's action are three views of the same underlying chemistry rather than three separate topics.
Watch for
Treating the rate law, the two-step mechanism, the activation energy, and the catalyst's effect as four unrelated facts about this reaction, rather than four consequences of the same rate-determining collision between one NO2 and one F2 molecule, is exactly the fragmented reading this capstone is built to correct.
