Extracurricular laboratory: Synthetic route of 76240-49-8

Any one of these steps may be slow and thus may serve as the rate determining step. In general, however, in the presence of the catalyst, the overall rate of the reaction is faster than it would be if the reactants were in the gas or liquid phase., 76240-49-8
