Deriving a rate law from a reaction mechanism

WebA rate law shows how the rate of a chemical reaction depends on reactant concentration. For a reaction such as aA → products, the rate law generally has the form rate = k[A]ⁿ, where k is a proportionality constant called the rate constant and n is the order of the reaction with respect to A. The value of n is not related to the reaction stoichiometry … WebIn the standard form, the rate law equation is written as: R = k [A] n [B] m R is reaction rate, expressed in concentration/unit of time (usually M/s = molarity/second) k is the specific …
