Final answer:

The rate law for the reaction 2A + B ⇒ C, which is zero order in both reactants, is simply 'rate = k', indicating that the reaction rate is constant regardless of the concentrations of A and B.

Step-by-step explanation:

The rate law for the reaction 2A + B ⇒ C, which is zero order in both A and B, is rate = k. In zero order reactions, the rate is constant and independent of the concentration of the reactants. This means that the reaction rate does not change with varying concentrations of A or B, and the rate constant k solely determines the reaction rate. The zeroth order nature of reaction implies that the reaction rate has the exponent of 0 for reactants A and B in the rate law expression.

In a zeroth-order reaction, the rate of the reaction is independent of the concentration of the reactants. This means that even if the concentration of A or B changes, the rate of the reaction remains constant. This is because the exponent of the reactant in the rate law is 0. Therefore, regardless of the concentrations of A and B, the reaction rate will remain the same -- it is only determined by the rate constant k.
