Abstract: The true reaction order, detd. from initial rates by the differential method, with respect to the concn. of Cr²⁺ is lower than the reaction order detd. by both the integral and the differential methods with respect to time. Product Cr³⁺ ions retard the redox reaction of Cr²⁺ with salicylaldehyde and the rate of increase of Cr³⁺ products corresponds to the rate of decrease of Cr²⁺ ions. The effect of a reversible reaction in the rate-detg. step of this noncomplementary redox reaction is discussed.
