What is the rate law for the reaction A + B → products, if the reaction is first-order in A and zero-order in B?

A. Rate = k[A]
B. Rate = k[A][B]
C. Rate = k[B]
D. Rate = k[A]²[B]

Answer: Rate = k[A]


Additional Information: For a first-order reaction in A and zero-order in B, the rate law depends only on [A].
