INDUCTION PERIODS OF CHEMICAL PROCESSES

An induction period (IP), one of the important kinetic parameters of s elf-accelerating processes, was considered for the class of chain reac tions. The definition of IP was formulated, and other definitions of I P available in the literature were critically analyzed. The functional relation between IP and kinetic parameters of main steps of chain pro cesses was revealed. The agreement between the analytical expression o btained and the numerical solution of a system of kinetic equations an d experimental data was verified. The examples of using TP for reveali ng specific features of reaction mechanisms and determining rate const ants were presented.
