WebThe two-step mechanism below has been proposed for a reaction between nitrogen monoxide and molecular chlorine: Step 1: NO ( g) + Cl 2 ( g) ⇌ NOCl 2 ( g) fast Step 2: NOCl 2 ( g) + NO ( g) 2NOCl ( g) slow Use this mechanism to derive the equation and predicted rate law for the overall reaction. Solution WebFor example in the equation provided above, step 1 is the slow step, and step 2 is faster. The slower step is used as the rate-determining step—because the rate of reaction can only go …

WebThe slower step is used as the rate-determining step —because the rate of reaction can only go as fast as the slowest step. You would use the rate-determining step to write the rate law by using its reactants. R = k [NO 2 ] [NO 2] or R = k [NO 2] 2 The rate law does not include CO (the second reactant in the original chemical equation). WebStep 1: Step 2: If step 1 is the rate-determining step, then the rate law for that step will be the rate law for the overall reaction. The rate law for the slow step of the proposed mechanism agrees with the overall experimentally determined rate law. The IO − is present as an intermediate in the reaction.

WebSep 3, 2024 · The rate determining step in a reaction mechanism is the slowest step. It is characterized by its high activation energy.
