Slowest step in a reaction mechanism
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. WebbThe 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 …

Webbthis text. 7.3 Assess the validity of the following statement: the rate- determining step is the slowest step in a reaction mechanism. Exercises 7.10 The equilibrium constant for the … Webb17 jan. 2024 · Part c.ii Sample Response: Yes. Step 2 is slow; therefore, it is the rate-determining step of this mechanism. The rate law of this elementary reaction is rate = k [N₂O₄]. Because N₂O₄ is an intermediate, it cannot appear in the rate law of the overall reaction. Because Keq = [N₂O₄]/ [NO₂]² in step 1, [N₂O₄] = Keq [NO₂]².
WebbIt consists of two bimolecular elementary steps. Step 1: Step 2: If step 1 is the rate-determining step, then the rate law for that step will be the rate law for the overall … WebbThe total steps in the mechanism would then be- 2A → A2 (fast) A2 → 2A (fast) A2 + B → C + D (slow) If the rate at which the intermediate A 2 is formed from two molecules of A is the same as the rate at which A2 breaks up form a molecules, then these two reactions form a state of dynamic equilibrium.
WebbThe rate-determining step is the slowest step in a reaction mechanism. The molecularity of the elementary step, and the reactants involved, will determine what the rate law will be … WebbThe rate of a multi-step reaction is determined by the slowest elementary step, which is known as the rate-determining step. The determination of a reaction mechanism can …
