Stationary Kinetic Structures of Chemical Reactions¹

Abstract—Stationary structures corresponding to non-stationary experiments with different initial conditions have been established for multistage reactions. Such structures are formed from various pairs of combinations of non-stationary reagent concentrations, and they remain constant over time in the course of reaction. They form lines of different curvature intersecting at one stationary point on the graphs of their concentration dependences for any reagent in one of the experiments. The stationary structures constructed in this way are specific for various reaction mechanisms; they supplement known relaxation characteristics and can be used to identify the mechanisms of chemical reactions based on the data of non-stationary experiments.
