For a reaction: `nA rarr` Product, if the rate constant and the rate of reactant are equal what is the order of the reaction?

If the rate of the reaction is equal to the rate constant, the order of the reaction is

If the rate of the reaction id equal to the rate constant, the order of the reaction is

If the rate of the reaction is equal to the rate constant , the order of the reaction is

If the rate constant of a reaction is same as the rate of reaction at any concentration of reactant, what is the roder of reaction ?

(a) For a reaction , A+B rarr Product the rate law is given rate = k[A]^(1)[B]^(2) .What is the order of the reaction ? (b) write the unit of rate constant k for the first order reaction
