Reaction molecularity

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 ...
