    • We note that this same behavior was observed to a lesser extent for 1 and 3; i.e., increasing concentrations of CAN leads to a slight enhancement of reaction rates. The implication of this result is that the rate law expression may be better described as a mixture of first- and second-order kinetic behavior; e.g., rate = k [Ru] + k ′[Ru][CAN]
