“…18 The measurements were performed on a Zeiss DMR 10 spectrophotometer equipped with a thermostatted (±0.1 0c) high-pressure cell. 7 The average value of K at normal pressure is (2.24 ± 0.14 X 10 3 M -I, which is in close agreement with the values (2.63 ± 0.1) X 10 3 and (2.14 ± 0.06) X 10 3 M-I reported in the literature. 16 Table I In conclusion, it can be said that very similar effects are observed with a joule-heating temperature-jump system than with a laser heated analog when inorganic complex formation processes of the type investigated, are studied.…”

This paper describes the construction and testing of a high-pressure joule-heating temperaturejump apparatus for the study of fast reactions in solution at pressures up to 2 kbar. Important features are: a liquid pressurizing medium; a Teflon membrane pressure transmitting device; a constant, pressure independent, electrode distance. The Co(II)-PADA reaction was used to test the system, and the results are in good agreement with earlier reported data.

“…All kinetic measurements at ambient pressure were performed on a Durrum D110 stopped-flow instrument. For the high-pressure measurements, a homemade high-pressure stopped-flow system was used. , All instruments were thermostated at ±0.1 °C. The kinetic traces, consisting of 1000 points per trace, were collected and stored on an IBM-compatible computer using Biologic (Claix, France) software.…”

Comparative Kinetic Analysis of Reversible Intermolecular Electron-Transfer Reactions between a Series of Pentaammineruthenium Complexes and Cytochromec

et al. 1996

In this kinetic and thermodynamic study, the reversible outer-sphere electron-transfer reactions between a series of Ru(NH(3))(5)L(3+/2+) complexes (L = etpy, py, lut) (etpy = 4-ethylpyridine; py = pyridine; lut = 3,5-lutidine) and cytochrome c were investigated as a function of ionic strength, buffer, pH, temperature, and pressure. Due to the low driving forces of these systems, it was possible to study all the reactions in both redox directions. The observed rate constants for various L are correlated on the basis of the ability of ligands on the ruthenium complex to penetrate the heme groove on cytochrome c. The measurements as a function of pressure enabled the construction of volume profiles for all investigated systems. The activation volumes for all of these processes are very similar: between -14.9 and -17.8 cm(3) mol(-)(1) for the reduction and between +14.7 and +17.8 cm(3) mol(-)(1) for the oxidation of the protein by Ru(NH(3))(5)L(2+/)(3+), respectively. The overall reaction volume varies between 27 and 35 cm(3) mol(-)(1), from which it follows that the transition state lies exactly halfway between reactant and product states on a volume basis in all cases. There is good agreement throughout between kinetic and thermodynamic data.

High pressure cells for the study of optical properties of liquid systems

Abstract: In order to investigate optical properties of liquid systems under high pressure two cells were constructed and tested. Special attention was given to the possibility of investigating equilibria or rates of reactions of corroding liquids.
