Equations for rate law

WebSince step 1 limits the overall rate of the reaction, the rate law for this step will be the same as the overall rate law. The predicted rate law for the overall reaction is therefore. \text {rate} = k [\ce {NO2}]^2 rate = k[NOX 2]2. This rate law is in agreement with the experimentally-determined rate law we saw earlier, so the mechanism also ... 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.
