Book Description
An apparatus for rapidly mixing two solutions and recording the light absorption, which was developed by Connick and Below, has been modified. The mixing characteristics were studied and models were developed in an attempt to umder stand the observed mixing phenomena. The apparatus was applied to a study of the kinetics of the reactions Fe/sup +++/ + SCN/sup -/ = FeSCN/sup ++/ and Fe/ sup +++/ Cl/sup -/ = FeCl/sup ++/ in aqueous solution, with both reactions having the forward rate law STAd(FeX/sup ++/)/dt = k/sub 1/ (Fe/sup +++/) (X/sup -/) + k/ sub 2/ (Fe/sup +++/)(X/sup -/)/(H/sup +)!, where X/sup -/ represents either SC N/ sup -/ or Cl/sup -/. The rate constants k/sub 1/ and k/sub 2/ have been measured as a function of temperature, and the heats and entropies of activation have been calculated. Mechanisms for the observed rate law have been discussed and the entropies of activation were compared with those for analogous reaction rates and with some equilibrium entropies of complexing. A rate for chloride complexing of ferric ion was obtained from nuclear magnetic resonance studies and compared with the results of the spectrophotometric kinetic study. (auth).
The Iron(III) Thiocyanate Reaction
Author: Kevin C. de BergPublisher: Springer Nature
ISBN: 3030273164
Category : Science
Languages : en
Pages : 99
Book Description
This Brief presents an historical investigation into the reaction between ferric ions and thiocyanate ions, which has been viewed in different ways throughout the last two centuries. Historically, the reaction was used in chemical analysis and to highlight the nature of chemical reactions, the laws of chemistry, models and theories of chemistry, chemical nomenclature, mathematics and data analysis, and instrumentation, which are important ingredients of what one might call the nature of chemistry. Using the history of the iron(III) thiocyanate reaction as a basis, the book’s main objective is to explore how chemistry develops its own knowledge base; how it assesses the reliability of that base; and how some important tools of the trade have been brought to bear on a chemical reaction to achieve understanding, a worthwhile goal of any historical investigation.

Kinetics of Inorganic Reactions
Author: A. G. SykesPublisher: Elsevier
ISBN: 1483185672
Category : Science
Languages : en
Pages : 319
Book Description
Kinetics of Inorganic Reactions provides a comprehensive account of the mechanisms of inorganic reaction. The book is comprised of 15 chapters that deal with the two main fields of inorganic reaction, the homogeneous gas-phase reactions and solution reactions. The first chapter of the text provides an introduction to some of the basic concepts in inorganic reaction, which include the mechanisms of a reaction, reactions in different phases, and the feasibilities of a reaction. Next, the book details the experimental techniques and treatment of data. The next series of chapters talks about gas-phase reactions. The book also dedicates a chapter in covering various types of reactions, including isotopic reaction and redox reaction. Chapters 12 to 14 deal with substitution reactions, while Chapter 15 talks about acid-base reactions. The text will be most useful to chemists and chemical engineers, particularly those who deal with inorganic chemistry.
