WebSep 7, 2024 · What is the overall rate law? A 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. WebAnd because the reaction is first order with respect to each reactant, the initial rate of the reaction would be 5.46 × 10 −12 mol L 1 s 1, which is three times the rate of the initial rate of the reaction in Experiment 1.
