The rate of a chemical reaction is determined by the slowest step. Rate = k[Concentration of reactants individually raised to their stoichiometric co-efficients] In mechanism I, Overall reaction occurs in a … Webb26 sep. 2024 · The elementary step that has a rate law that matches the overall reaction’s rate law is the slow rate-determining step. How many steps are in a mechanism? Answer and Explanation: Any reaction mechanism have two or more steps therefore the reaction mechanisms will always have a minimum of 2 steps.

Webb16 mars 2024 · To identify the slow step and the reaction mechanisms, you need to consider: 1) the sum of elementary steps = overall reaction 2) the mechanisms must agree with the experimentally determined rate law. Whichever elementary step has a rate law that matches the overall reaction's rate law is the slow step. The slow step determines the … Webb27 mars 2014 · A useful reaction mechanism. consists of a series of elementary steps (defined below) that can be written as chemical equations, and whose sum gives the net balanced reaction equation;; must agree with the experimental rate law; can rarely if ever be proved absolutely.
