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. 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.
