Quizplus · Accepted Answer

The rate law is determined by analyzing the order of each reactant in the reaction based on the given data. From the table, it can be observed that when the concentration of A is doubled and the concentration of B remains constant, the rate also doubles. This indicates that the reaction is first order with respect to A. Similarly, when the concentration of B is doubled and the concentration of A remains constant, the rate increases by a factor of 2.8, which suggests that the reaction is approximately 1.5 order with respect to B. Therefore, the correct rate law is Rate = k[A]^1[B]^1.5, which can be simplified as Rate = k[A][B]^1.5. The closest option to this rate law is E, Rate = k[A]^(1.2)[B].
