If the rate law of a reaction rate is k[x]^0[y]^0, it means that the rate of the reaction does not depend on the concentration of either reactant. This can occur in zero-order reactions where the rate is independent of the concentration of the reactants.
The units of k will depend on the overall order of the reaction. In this case, the overall order of the reaction is zero. When the overall order is zero, the units of k are in concentration/time, typically expressed as M/s.
What are the units of k if the rate law of a reaction rate is k[x]^0[y]^0
