The solution-phase kinetics of the reaction of cuprous chloride with molecular oxygen in pyridine were studied by monitoring product formation.The reaction was found to be third order in cuprous chloride and first order in oxygen by initial rate studies and pseudo-first-order rate constant determinations.A single rate law was found for solutions in which initial cuprous chloride concentrations were varied by more than a factor of 350 and initial oxygen concentrations were varied by more than a factor of 40.The integrated form of the resulting rate expression was found to precisely predict product vs. time curves.A more limited kinetic study of the reaction of cuprous acetate with oxygen in pyridine demonstrated that this reaction is first order in oxygen and second order in cuprous acetate.
