WebFor example, if m = 1 and n = 2, the reaction is first order in A and second order in B. The overall reaction order is simply the sum of orders for each reactant. For the example rate law here, the reaction is third order overall (1 + 2 = 3). A few specific examples are shown below to further illustrate this concept. The rate law: WebThe overall order of a reaction is the sum of the orders with respect to each reactant in the rate law. Explanation: The order with respect to a reactant can be determined experimentally by measuring the rate of the reaction under different conditions, while keeping the concentration of other reactants constant.
