    Description / Table of Contents: Abstract Была составлена программа для настольного ЭВМ, написанная языком BASIC для оптимализации величин констант скоростей, определяемых из данных измерений кинетики реакций в зависимости от времени и концентраций. Программа способна симультативно уточнять максимально 5 констант скорестей. FORTRAN текст на основе метода Гира также доступен.
    Notes: Abstract A desk computer program has been written in BASIC programming language to optimize the values of rate constants determined from kinetic measurements of time and concentration data. The program is capable of the simultaneous refinement of a maximum of 5 rate constants. A FORTRAN version using the Gear method is also available.

    Kinetics of the rapid interaction of chromium(III) with iodate and sulfite (1975)

    Description / Table of Contents: Abstract Техника релаксации была использована для изучения кинетики быстрого взаимодействия Cr(III) с иодатом и сульфитом. Данные скорости и H+-каталиэ укаэывают на то, что комплексообразование протекает согласно механизму кислородного обмена, который, однако, не включает в себя разрыв связи Cr(III)-o.
    Notes: Abstract Relaxation techniques have been used to study the kinetics of the rapid interaction of Cr(III) with iodate and sulfite. Rate data and H+-catalysis indicate that complex formation occurs via an oxygen exchange mechanisms which does not involve Cr(III)-O bond breaking.

    Artifacts caused by plastics in chemical experiments: Absorption, degradation, catalysis and irreproducible behavior (1991)

    Description / Table of Contents: Abstract На практике нашей лаборатории мы были поражены некоторыми неконтролируемыми результатами, вызванными пластмассами. Последние обычно считают химически более или менее нереактивными и инертными. Абсорбция и химическое разложение — особенно во время продолжительного использования — могут активировать поверхность силиконов, полиэтилена или тефлона, материалов, из которых изготовлены трубки, реакционные сосуды, стержни для мешалок и другие части оборудования. В некоторых случаях каталитическую активность интерпретируют, исходя из взаимодействия микропор поверхности пластмасс с реагентами. Эти наблюдения заставляют нас особенно внимательно выбирать и контролировать пластмассы по их свойствам и качеству даже в самых простейших химических экспериментах.
    Notes: Abstract In the experimental praxis of our chemical laboratory we have been surprised and impressed by a few uncontrollable results caused by plastics. These materials are generally considered to be chemically more or less unreactive and inert. Absorption and chemical degradation—especially during long use—can activate the surface of silicon rubber, polyethylene or teflon, which are constituents of tubes, reaction vessels, stirring bars and other parts of instruments. In a few cases catalytic activation can be interpreted in terms of the interaction between the microporous surfaces of plastics and reactants. These observations require careful consideration and control of the properties and quality of plastics before using them even in the simplest chemical experiments.

    Notes: According to our experiments the bromide ion concentration exhibits in the bromate-ascorbic acid-malonic acid-perchloric acid system three extrema as a function of time. To describe this peculiar phenomenon, the kinetics of four component reactions have been studied separately. The following rate equations were obtained:Bromate-ascorbic acid reaction: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{*{20}c} { - d[{\rm BrO}_3^ -]/dt = k_1 [{\rm BrO}_3][{\rm H}_2 {\rm A],}} & {k_1 = 8.3 \times 10^{ - 3} M^{ - 1} \cdot {\rm s}^{ - {\rm 1}} } \\ \end{array} $$\end{document}Bromate-bromide ion reaction: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{*{20}c} { - d[{\rm BrO}_3^ -]/dt = k_2 [{\rm BrO}_3][{\rm Br}^ -][{\rm H}^ +]^2,} & {k_2 = 3.6M^{ - 3} \cdot {\rm s}^{ - 1} } \\ \end{array} $$\end{document}Bromide-ascorbic acid reaction: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{*{20}c} { - d[{\rm Br}_{\rm 2}]/dt = k_3 [{\rm Br}_2][{\rm H}_2 {\rm A],}} & {k_3 \ge 1.7 \times 10^{ - 3} \cdot {\rm s}^{ - 1} } \\ \end{array} $$\end{document}Bromine-malonic acid reaction: \documentclass{article}\pagestyle{empty}\begin{document}$$ \begin{array}{*{20}c} { - d[{\rm Br}_{\rm 2}]/dt = k_4 k_4 [{\rm Br}_2][{\rm H}_2 {\rm M}]/(k_4 + k_5 [{\rm Br}_2]),} & {k_4 = 6 \times 10^{ - 3} {\rm s}^{ - 1} } \\ \end{array}, \quad {\rm }k_{ - 4} \ge 1.7 \times 10^{ - 3} \cdot {\rm s}^{ - 1} \quad {\rm }k_5 \ge 1 \times 10^7 M^{ - 1} \cdot {\rm s}^{ - 1} $$\end{document} k4 = 6 × 10-3 s-1, k-4 ≥ 1.7 × 103 s-1, k5 ≥ 1 × 107M-1 · s-1Taking into account the stoichiometry of the component reactions and using these rate equations, the concentration versus time curves of the composite system were calculated. Although the agreement is not as good as in the case of the component reactions, it is remarkable that this kinetic structure exhibits the three extrema found.
