A reaction is thought to be second order with respect to the concentration of carbon monoxide. What evidence would support this?
Answer options...
A. Changing the initial concentration would have no effect on the rate.
B. Any change in the initial concentration would cause a directly proportional change in the rate.
C. Reducing the initial concentration to one-third of the original value would decrease the rate to one-third of the original rate.
D. Doubling the initial concentration would increase the rate of the reaction by four times.
