This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer WebbQuestion: In the overall reaction that produces nitric oxide from N_2 and O_2 the slow step in the mechanism is the reaction between atomic oxygen and molecular nitrogen to produce nitric oxide and atomic nitrogen. Write out the chemical equation for the slow step and the rate law equation for it.

Webb14 mars 2024 · Hi, The slow step is the rate determining step because it dictates how fast the reaction can go overall. For instance, if we assume the initial rates of Step 1 and Step 3 are 50 M/s and 60 M/s respectively, yet Step 2 is proceeding at 20 M/s the reaction cannot go faster than 20 M/s because the slowest step in a sense controls the other steps. WebbThe 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 …

Webb16 mars 2024 · To identify the slow step and the reaction mechanisms, you need to consider: 1) the sum of elementary steps = overall reaction 2) the mechanisms must agree with the experimentally determined rate law. Whichever elementary step has a rate law that matches the overall reaction's rate law is the slow step. The slow step determines the …
