A reaction was found to be second order with respect to the concentration of carbon monoxide. If the concentration of carbon monoxide is doubled, with everything else kept the same, the rate of reaction will
  1. (A)remain unchanged
  2. (B)triple
  3. (C)increase by a factor of 4✓ Correct
  4. (D)double

Answer: (C)

Solution

Being second order in carbon monoxide means the rate follows . Doubling the concentration replaces by , so the rate becomes , four times its original value. The rate therefore increases by a factor of four.
