Doubling [A] doubles the rate; doubling [B] leaves the rate unchanged. What is the rate law?

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

Explanation

Core Concept

Rate doubling with [A] means first order in A; no change with [B] means zero order in B. Zero-order species drop out of the rate law.

Correct Answer

Arate = k[A]
