Couples Containing Aromatic Ligands written by Saeed Sahami and published by . This book was released on 1981 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Variations in the solvent medium are generally expected to yield profound changes in the thermodynamics and kinetics of electron transfer reactions. The origins of the observed solvent effects are frequently manifold, arising from alterations in the chemical nature of the reacting species as well as the reactant-solvent interactions in both the ground reactant and transition states. We have embarked on a systematic study of solvent effects upon the electrode kinetics and thermodynamics of redox couples involving substitutionally inert cations where the oxidized and reduced species are both stable in the solution phase and differ only by one electron.
Book Synopsis Solvent Effects on the Kinetics of Simple Electrochemical Reactions. I. Comparison of the Behavior of Co(III)/(II) Trisethylenediamine and Ammine Couples with the Predictions of Dielectric Continuum Theory by : Saeed Sahami

Comparison of the Behavior of Co(III)/(II) Trisethylenediamine and Ammine Couples with the Predictions of Dielectric Continuum Theory written by Saeed Sahami and published by . This book was released on 1981 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electroreduction kinetics of Co(en)3(3+) (en = enthylenediamine), Co(NH3)6(3+), and Co(NH3)5F(2+) have been investigated at mercury electrodes in aqueous solution and six nonaqueous solvents in order to explore the influence of the solvent upon the electrode kinetics of such simple one-electron outer-sphere reactions where the composition of the reactant's coordination sphere remains fixed. Substantial variations in the experimental rate parameters were observed as the solvent was altered; these reflect the influence of the outer-shell solvent upon the reorganization barrier to electron transfer. A simple phenomenological treatment of solvent effects upon the electrode kinetics of such simple redox reactions is given. It is pointed out that double-layer corrected rate constants kcorr can be evaluated at the same Galvani potential in different solvents with useful accuracy; these quantities can provide particular insight into the chemical influence of the solvent. The utility of separating such solvent effects into intrinsic and thermodynamic contributions is noted. The substantial decreases in kcorr seen when substituting several nonaqueous solvents for water were traced to increases in the outer-shell component of the intrinsic free energy barrier.

Couples Containing Ammine and Ethylenediamine Ligands written by Saeed Sahami and published by . This book was released on 1981 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have been examining the solvent dependence of the thermodynamics of simple transition-metal redox couples as part of an experimental program exploring the role of the solvent in the kinetics and thermodynamics of outer-sphere electron transfer reactions. One-electron redox couples containing substitutionally inert complexes form especially tractable systems for this purpose since the influence of variations in the outer-shell solvent contributions can be assessed separately from the inner-shell (metal-ligand coordination shell) effects. Our general approach is to determine the formal potential Ef of each redox couple in a range of solvents having suitably varied chemical and physical properties. In addition, the temperature dependence of Ef is monitored in each solvent using a nonisothermal cell arrangement, yielding values of the reaction entropy of the redox couple equals the difference between the absolute ionic entropies of the reduced and oxidized forms. These measurements yield estimates of the free energy, entropy, and enthalpy of transferring the redox couple from water to other solvents.

This book was released on 1983 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective is to develop our understanding of the connections between the kinetics and mechanisms of heterogeneous electron-transfer reactions at metal-electrolyte interfaces and the molecular structure of the reactant and the interfacial region. We have chiefly focussed attention on transition-metal redox couples, especially Co(III)/(II), Cr(III)/(II), and Ru(III)/(II) containing adsorbing inorganic and organic ligands at a number of electrocatalytic solid surfaces, especially silver, platinum, and gold, as well as at mercury electrodes. By combining electrochemical kinetic and reactant adsorption thermodynamic measurements, along with in situ vibrational spectroscopic studies using Surface-Enhanced Raman Scattering (SERS), the various catalytic influences exerted by the metal interface upon the energetics of electrode reactions have been probed in detail.

Book Synopsis Solvent Effects Upon Electrochemical Kinetics: Influences of Interfacial Solvation and Solvent Relaxation Dynamics by : M. J. Weaver
Download or read book Solvent Effects Upon Electrochemical Kinetics: Influences of Interfacial Solvation and Solvent Relaxation Dynamics written by M. J. Weaver and published by . This book was released on 1984 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper is intended as a summary of some recent research aimed at gaining a fundamental understanding of solvent effects in electrochemical kinetics. Besides examining the effects of altering the bulk solvent, experiments are also described where the influence of the interfacial solvent structure in aqueous media is probed through variations in the hydrophility of the metal surface. Particularly since some of this recent experimental activity has been associated closely with concurrent theoretical development, it is useful to provide a brief summary of the underlying kinetic formulations.

Download or read book Electrochemistry in Ionic Liquids written by Angel A. J. Torriero and published by Springer. This book was released on 2015-07-17 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a set of two books dedicated to presenting the latest novel and advanced research from around the world in this exciting area. These books highlight the important properties of electrochemistry in ionic liquids – as opposed to the more commonly used aqueous and organic environments – and the many applications. Readers will find 20 chapters gathered in two books : Electrochemistry in Ionic Liquids – Volume 1, Fundamentals: This book critically discusses electrode-electrolyte interfacial processes, reference electrodes, ultramicroelectrode voltammetry and scanning electrochemical microscopy, semi-integral and convolution voltammetry, and small-angle X-ray scattering coupled with voltammetry. The structure and properties of protic ionic liquids, deep-eutectic solvents, task-specific ionic liquids, polymeric ion gels, and lithium-ion solvation, useful for electrochemical application is also critically discussed. Electrochemistry in Ionic Liquids – Volume 2, Applications: The major topics covered in this book include electrodeposition and electroless deposition, voltammetry of adhered microparticles, electrochemistry of organic and organometallic compounds, electrocatalytic reactions, oxygen reduction reaction, ionic liquids in surface protection and lubrication, current industrial application of ionic liquids, and challenges, issues and recycling methods of ionic liquids in industrial developments.
