The rate constants increase with the increase in the excess of one of the reactants. The change in the effective rate constants is described by the Michaelis–Menten equation indicating that the reaction proceeds through the initial equilibrium stage of formation of an intermediate complex which then transforms into the product. The effective rate constants, the equilibrium constants of formation of the intermediate complex, and the rate constant of its transformation into the reaction product were determined, as well as the thermodynamic parameters of the formation of the intermediate complex and the activation parameters of the transformation of the intermediate complex into the product. The limiting stage of the reaction is established and its mechanism is suggested.Item Unquality advertising in Ukrainian printed media(Lviv Polytechnic Publishing House, 2015) Kitsa, Mariana; Lviv Polytechnic National UniversityIn the article there are analised different kinds of advertising in regional Ukrainian press.
