Webb9 sep. 2024 · The slowest step in a reaction mechanism is known as the rate-determining step. The rate-determining step limits the overall rate and therefore determines the rate … WebbThe second mechanism, however, does agree with the ST geometry, but not with the rate law we can take the two steps that are provided and some them together and see that we do get the overall reaction of a plus to be goes to C plus D. The slow step is the rate determining step, which defines the rate so rate will be equal to.

How do you determine which step is the rate determining step?

WebbMatch these terms with the descriptions below. A term can be used more than once or not at all. a. reaction intermediates f. reaction mechanism b. activation energy g. catalysts c. … WebbFor multi-step mechanisms, there is often one step that is significantly slower than the other steps. This slowest step is referred to as the rate-determining step, as it limits the rate of the entire reaction. An analogy that illustrates this concept is an hourglass having two different sized openings. biographical sermon
