An equation describing the dissociation during the period of reaction acceleration was derived with the postulate that the reaction nuclei during the dissociation of explosives form as the result of the interaction of atoms or of radicals originating during the reaction with the molecules of the unreacted matter. The value for the exponent in the kinetic equation p kt to the m power, once being applied to describe the dissociation rate of explosives, cannot be explained by the number of intermediate stages or the number of electrons necessary for the formation of a stable nucleus, as was considered by Mott Proc. Roy. Soc. A, 172, 325, 1939, since the value of m depends on the degree of dispersion of the dissociating matter. Among the explosives discussed are the azides of lead, barium, calcium, and lead, and mercury fulminate.
