Change in the composition of radicals in a complex chain reaction

Summary

  1. 1.

    In complex chain reactions involving the formation of molecular intermediate products, the composition of the radicals inevitably changes during the reaction due to the change in the composition of the products. A general solution was obtained in the present work for the problem of the change in the rate of a complex chain reaction due to a change in the composition of the radicals for the case of several active centers.

  2. 2.

    The appearance of more active radicals in the reaction mixture may increase the reaction rate by a limited factor, while the appearance of radicals of low activity may retard the chain reaction very strongly.

  3. 3.

    Radicals which react very slowly with each other accelerate the reaction by a limited factor, while radicals which react with each other rapidly may retard the reaction very strongly.
