Final answer:
The order of reaction with respect to A is 1 and the order of reaction with respect to B is also 1. The rate law for the reaction is rate = k[A][B].
Step-by-step explanation:
The order of reaction with respect to A is 1 (x=1) and the order of reaction with respect to B is also 1 (y=1). Therefore, the rate law for the reaction is rate = k[A][B]. The reaction is a second-order reaction overall.
