define activity in chemistry: Atkins' Physical Chemistry 11e Peter Atkins, Julio De Paula, James Keeler, 2019-09-06 Atkins' Physical Chemistry: Molecular Thermodynamics and Kinetics is designed for use on the second semester of a quantum-first physical chemistry course. Based on the hugely popular Atkins' Physical Chemistry, this volume approaches molecular thermodynamics with the assumption that students will have studied quantum mechanics in their first semester. The exceptional quality of previous editions has been built upon to make this new edition of Atkins' Physical Chemistry even more closely suited to the needs of both lecturers and students. Re-organised into discrete 'topics', the text is more flexible to teach from and more readable for students. Now in its eleventh edition, the text has been enhanced with additional learning features and maths support to demonstrate the absolute centrality of mathematics to physical chemistry. Increasing the digestibility of the text in this new approach, the reader is brought to a question, then the math is used to show how it can be answered and progress made. The expanded and redistributed maths support also includes new 'Chemist's toolkits' which provide students with succinct reminders of mathematical concepts and techniques right where they need them. Checklists of key concepts at the end of each topic add to the extensive learning support provided throughout the book, to reinforce the main take-home messages in each section. The coupling of the broad coverage of the subject with a structure and use of pedagogy that is even more innovative will ensure Atkins' Physical Chemistry remains the textbook of choice for studying physical chemistry. |
define activity in chemistry: Physical Chemistry for the Biosciences Raymond Chang, 2005-02-11 This book is ideal for use in a one-semester introductory course in physical chemistry for students of life sciences. The author's aim is to emphasize the understanding of physical concepts rather than focus on precise mathematical development or on actual experimental details. Subsequently, only basic skills of differential and integral calculus are required for understanding the equations. The end-of-chapter problems have both physiochemical and biological applications. |

define activity in chemistry: Physical Chemistry Kurt W. Kolasinski, 2016-11-14 In der Chemie geht es überwiegend um die Frage: Wie? Wie wird primärer Alkohol hergestellt? Durch Reaktion eines Grignard-Reagenz mit Formaldehyd. In der physikalischen Chemie lautet die Frage: Warum? Das Grignard-Reagenz und Formaldehyd tanzen auf Molekülebene. Man spricht von einem Reaktionsmechanismus, bei dem stärkere Verbindungen schwächere Verbindungen vom Parkett fegen. Wenn Sie wissen möchten, warum das so ist, ist dieses Buch genau richtig. Physical Chemistry: How Chemistry Works verfolgt einen neuen Ansatz bei der Vermittlung der Lerninhalte rund um die physikalische Chemie. Dieses moderne Lehrbuch soll Chemiestudenten im Hauptstudium für das Fachgebiet begeistern und auf die Anwendung der physikalischen Chemie in der Praxis vorbereiten. Praxisorientiert, leserfreundlich und modern sind die Beispiele, mit denen sich die physikalisch-chemischen Aspekte jedes Systems besser verstehen lassen. Studenten der anorganischen Chemie, organischen Chemie, analytischen Chemie und Biochemie erfahren alles Wissenswerte über die physikalische Chemie und wissen im Anschluss, was Synthesen, intermolekularen Wechselwirkungen und Materialeigenschaften sind. Studenten, die sich eingehender mit der physikalischen Chemie beschäftigen möchten, erleichtert dieses Lehrbuch diesen Schritt, denn es zeigt auch die Grenzen der Forschung auf. |

define activity in chemistry: Water Chemistry Patrick Brezonik, William Arnold, 2011-03-22 Water Chemistry provides students with the tools necessary to understand the processes that control the chemical species present in waters of both natural and engineered systems. After providing basic information about water itself and the chemical composition of water in environmental systems, the text covers the necessary theory (thermodynamics, activity, and kinetics) and background material to solve problems. It emphasizes that both equilibrium and kinetic processes are important in aquatic systems. The book does not merely focus on inorganic constituents, but also on the fate and reactions of organic chemicals. The solving of quantitative equilibrium and kinetic problems using mathematical, graphical, and computational tools is emphasized throughout presentations on acid-base chemistry, complexation of metal ions, solubility of minerals, and oxidation-reduction reactions. The use of these problem-solving tools is then extended in the presentation of topics relevant to natural systems, including dissolved oxygen, nutrient chemistry, geochemical controls on chemical composition, photochemistry, and natural organic matter. The kinetics and equilibria relevant to engineered systems (e.g., chlorination and disinfection chemistry, sorption and surface chemistry) and organic contaminant chemistry are also discussed. Numerous in-chapter examples that show the application of theory and demonstrate how problems are solved using algebraic, graphical, and computer-based techniques are included. Examples are relevant to both natural waters and engineered systems. |

define activity in chemistry: International Symposium on Selective Ion-Sensitive Electrodes G. J. Moody, 2013-10-22 International Symposium on Selective Ion-Sensitive Electrodes contains the plenary lectures presented at the International Symposium on Selective Ion-Sensitive Electrodes, held in Cardiff, UK on April 9-12, 1973 and organized by the International Union of Pure and Applied Chemistry. The papers explore significant developments concerning selective ion-sensitive electrodes and cover topics ranging from potentiometric gas sensing electrodes to precipitate-based selective ion-sensitive electrodes and mechanistic aspects of ion-selective membrane electrodes. This book is comprised of five chapters and begins by introducing the reader to ion activity scales for use with selective ion-sensitive electrodes. Ion activities in dilute solutions, concentrated solutions, and mixtures of electrolytes are described. Attention then turns to the use of carrier antibiotics and model compounds as components of selective ion-sensitive electrodes. The next chapter focuses on a number of precipitate-based electrodes based for example on mixtures of metal chalcogenides, as well as enzyme electrodes and coated wire electrodes. Their analytical application in the widest sense is reviewed for anions and cations. This book also considers techniques used in elucidating glass, liquid, and crystal membrane electrode operation, along with their possible mechanisms. The final chapter analyzes a number of potentiometric gas sensing electrodes using hydrogen or other ion sensing electrode and a gas permeable membrane. This book will be of interest to students and practitioners of chemistry, biochemistry, and electrochemistry. |
