The absorbance-time dependence has been derived for a repeated arbitrary feed of one reaction component into solution of the other component controlled by the feedback. On the basis of the expressions derived, methods have been suggested for determination of the rate constant of irreversible reaction of the IInd order, and they have been experimentaly tested on two reactions.
