Abstract
It is shown that for chemical reactions occurring in an open isothermal gradientless reactor, the stationary state for any stoichiometric total concentration of compounds is unique and stable, even if there are several stationary states for each of the compounds. Relationships are established that allow deriving the exact values of linear and nonlinear relaxation times of reactions, which determine, respectively, the rate and time of reaching a given neighborhood of a stationary state from the total stationary concentration of compounds for any moment of time relying on the stoichiometry of the staged reaction scheme. Examples of calculating the exact values of relaxation times for a number of reactions proceeding according to the kinetic laws of mass action and Marcelin–de Donder equations are considered.
