The rate law for a reaction that involved three reactants was investigated by using the initial-rate method. When the concentration of reactant A was doubled the rate of the reaction was doubled. When the concentration of reactant B was tripled the rate of the reaction was tripled. When the concentration of reactant C was halved the rate of the reaction was not affected. What is the rate law for this reaction?

Group of answer choices

Rate = k[A][B][C]

Rate = k[A][B]

Rate = k[A]²[B]³

Rate = k[A]²[B]³[C]

Rate = k[A]²[B]
