WebOct 7, 2024 · Chemical reaction rate is the speed at which reactants become products. As a general rule, heat speeds up the rate of a reaction. Heat affects molecules by making them move faster. Imagine a room full … 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 ... darlinghurst bookshopWebThe term fast reaction is best applied to reactions that cannot be followed kinetically by conventional methods.
