WebThe first step is unimolecular (one molecule of ozone reacts) and the second step is bimolecular (one ozone free radical and one ozone molecule react together). Summary … WebTools. In chemical kinetics, the overall rate of a reaction is often approximately determined by the slowest step, known as the rate-determining step ( RDS or RD-step [1] or r/d step [2] [3]) or rate-limiting step. For a given reaction mechanism, the prediction of the corresponding rate equation (for comparison with the experimental rate law ... WebFeb 22, 2024 · The slow step is always the rate determining step. Therefore, all steps after that we can ignore. Since the slow step is an elementary reaction, you can determine the rate law from the stoichiometric chemical equation. If the mechanism is given as a slow then fast step, we can go ahead and just use the slow step to determine rate law. boat trip around santorini

WebA reaction mechanism is the sequence of elementary steps by which a chemical reaction occurs. Many reaction mechanisms contain one step that is much slower than the others; this step is known as the rate-determining step. If the rate-determining step is the first step in a mechanism, the rate law for the overall reaction can be derived directly ...
