The reaction A(g) + B(g) C(g) has the following rate law: Rate = k[A]²[B]. If the concentration of A is tripled while the concentration of B is doubled, the rate will increase by a factor of ________.

According to the rate law, rate is directly proportional to [A]²[B]. If [A] is tripled, rate becomes 3k[A]²[B]. If [B] is doubled, rate becomes 3k[A]²[2B] = 6k[A]²[B] Therefore, the rate will increase by a factor of 6 × 3 = 18.
