Quizplus · Accepted Answer

The rate law expression shows that the reaction is second order with respect to both A and B (S1U1). This means that if the initial concentration of B is tripled while holding the initial concentration of A constant, the initial rate will increase by a factor of 9 (3^2). Therefore, the answer is choice C (27).
