Determination of the Rate Constants from Phase Delay Effect in Chemical Reactions

Abstract

A new method for the determination of rate constant k of a reaction of the type A + X → P1 + P2 is presented. The method is based on the phase delay between the oscillatory inflow of the parent substance X into the reaction medium and the concentration of the parent substance in the field changing as a result of the reaction, which can be expressed as tan φ = \(\frac{{2{\omega }}}{{kA}}\). A method was used for the determination of the rate constant of the saponification of ethyl acetate (reactant A) with sodium hydroxide (reactant X) at 17°C. Reactant A was used in excess with respect to reactant X, which ensured its constant concentration.
