WebThe rate determining step of a reaction is the slowest step in the mechanism. Obviously, if there’s only step that step is rate-determining (examples Sn2 E2, acid-base) (the majority … WebThe slower step is used as the rate-determining step —because the rate of reaction can only go as fast as the slowest step. You would use the rate-determining step to write the rate law by using its reactants. R = k [NO 2 ] [NO 2] or R = k [NO 2] 2 The rate law does not include CO (the second reactant in the original chemical equation).

Why is the rate determining step slow? + Example

WebExpert Answer. 100% (1 rating) Slowest step is generally formation of reaction intermediates Once reaction intermediates like carbocations carbanions etc are formed since they are very reactive they will react very fast to form product. Hence the fastest step is the step in …. View the full answer. onr diversity

Is the rate determining step the step with the largest Ea?

WebJan 25, 2024 · The slowest elementary step is therefore termed the rate-determining step. Thus, the number of atoms, ions, or molecules taking part in the slowest elementary step of a complex reaction is called the molecularity of the complex reaction. Let us understand the concept through the molecularity of reaction examples. WebSlowest step is generally formation of reaction intermediates Once reaction intermediates like carbocations carbanions etc are formed since they are very reactive they will react … WebThere are multiple ways to find which step is the slow/fast step without it being given to you. 1) Look at k. The smaller k is probably the slower step. 2) Look at the activation energy for each step. in year school transfer waltham forest
