WebThe rate-determining (slower) step gives a rate law showing second-order dependence on the NO 2 concentration, and the sum of the two equations gives the net overall reaction. In general, when the rate-determining (slower) step is the first step in a mechanism, the rate law for the overall reaction is the same as the rate law for this step. WebMar 5, 2024 · A catalyst is accounted for in the rate law because it speeds up the reaction. It isn't considered in a balanced chemical equation because it doesn't undergo any change, nor does it affect any of the reactants in anyway besides increasing the speed of the reaction. So basically, does the catalyst not react or interact with the reactants at all? Top

WebThe rate law will have the form: rate = k[NO]m[O3]n Determine the values of m, n, and k from the experimental data using the following three-part process: Step 1. Determine the value of m from the data in which [NO] varies and [O3] is constant. In the last three experiments, [NO] varies while [O 3] remains constant. WebThe rate law for this reaction should include the concentrations of iodide, hydrogen ion, and hydrogen perioxide. However, if the concentration of H+ is held constant throughout the experiment then its effect will not appear in the rate law. This results in a relatively simple rate law: rate = k[I–]n[H 2O2] m[H+]p simplifies to: rate = k'[I ...

WebThe reaction rate can depend on how concentrated our reactants are. A chemical reaction’s rate law is an equation that describes the relationship between the concentrations of reactants in the reaction and the reaction rate.
