At any electrode immersed in an electrolyte solution, a specific interfacial region is formed. This region is called the double layer. The electrical properties of such a layer are important, since they significantly affect the electrochemical measurements. In an electrical circuit used to measure the current that flows at a particular working electrode, the double layer can be viewed as a capacitor...
The wish to determine thermodynamic data of electrochemical reactions and of the involved compounds is one of the most important motivations to perform electrochemical measurements. After calorimetry, electrochemistry is the second most important tool to determine thermodynamic data. Although ab initio quantum chemical calculations can be used for the calculation of thermodynamic data of small molecules,...
It is a matter of common knowledge, not only in science but also in everyday life, that spontaneous processes can take place at different rates and that the velocity of chemical, physical, and biological changes can be influenced by a variation of the conditions (e.g., with an increase or decrease in temperature). Electrochemical reactions involve charged species whose energy depends on the potential...
