The reaction A + 2B → Products was found to follow the rate law: rate = k[A]²[B]. Predict by what factor the rate of reaction will increase when the concentration of A is doubled, the concentration of B is tripled, and the temperature remains constant.

Question

The rate law is rate = k[A]²[B]. If the concentration of A is doubled, the rate will increase by a factor of 2² = 4. If the concentration of B is tripled, the rate will increase by a factor of 3. Therefore, the overall increase in the rate will be 4 * 3 = 12.
