Slowest step in a reaction mechanism
Webb13 apr. 2024 · The reaction mechanism starts with the formation of cations, and alcohol acts as a nucleophile in the carbocation. In base catalysis, the protonation of the carbonyl group of the triglycerides occurs followed by an attack of the protonated carbon by the alcohol to form a tetrahedral intermediate ( Figure 3 b). 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.

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.
