WebSep 19, 2024 · A The rate law for step 1 is rate = k1 [NO 2] 2; for step 2, it is rate = k2 [N 2 O 4 ] [CO]. B If step 1 is slow (and therefore the rate-determining step), then the overall rate law for the reaction will be the same: rate = k1 [NO 2] 2. This is the same as the experimentally determined rate law.

WebFeb 13, 2024 · $\begingroup$ Just because the rate law matches the stoichiometry does not mean it is an elementary reaction. Lots of multi-step mechanisms would result in the same rate law. On the other hand, if you specify that a reaction is an elementary one, you can infer the rate law from the coefficients of the reaction as written. $\endgroup$ – embley half termWebThe rate-determining step of a reaction is the rate of the slowest elementary step of its mechanism Correct answer: All of the above Explanation: All of the above describe elementary reactions and how they give an overall mechanism.
