WebThe diffusional limiting rate for a bimolecular reaction is 10 8 to 10 9 M − 1 s − 1. The ratio of k cat /K m is a first-order rate constant. The product of k cat /K m and the substrate concentration (at subsaturating levels) yields the rate of the enzyme-catalyzed reaction. This rate is proportional to the substrate concentration and is ...

WebThis step is the rate-determining step of the reaction, and, because it involves only a molecule of the substrate, the reaction is unimolecular. The second stage of the reaction is the interaction of the intermediate carbonium ion with the nucleophile to give the products of the reaction. The unimolecular reaction is characterized ... WebHowever, our definition of molecularity states that we need to look at an elementary step and not the overall reaction. Data on the reaction mechanism shows us that the reaction occurs in two steps: Step 1: Step 2: So we see that each elementary step is bimolecular and not termolecular. Notice that the colliding molecules may be the same (as in ... WebIn chemical kinetics, the distance traveled is the change in the concentration of one of the components of the reaction.
