Final answer:
If the reaction rate is independent of the concentration of A, then the order of the reaction in chemical A (m) should be equal to zero. This means that the rate does not depend on the concentration of A.
Step-by-step explanation:
The reaction rate depends on the rate constant and the concentration of reactants raised to the powers m and n, which are the orders of the reaction in chemical A and chemical B, respectively. If the reaction rate, r, is independent of the concentration of A, then m should be equal to zero. This means that the reaction is zero order in A, and the rate does not depend on the concentration of A.
For example, if the rate law is given by rate = k[A]^m[B]^n, and the rate is independent of [A], then m = 0. The overall reaction order is the sum of the reaction orders for each reactant, so the overall reaction order would be n.
It is important to note that the reaction order is determined experimentally and is not related to the stoichiometric coefficients in the balanced chemical equation.
