Electrochemistry standard cell voltage

The change of the cell voltage as a function of the cell temperature (temperature coefficient) dEf fdT = -0.83xl0-4 VK 1 and the relationship between the standard reaction entropy and the standard free enthalpy of reaction (3AG /3T)p = -AS the value for the cell reaction can be calculated as -AS = -16.02 J K-1 mol-1.

At the heart of electrochemistry is the electrochemical cell. We will consider the creation of an electrochemical cell from the joining of two half-cells. When an electrical conductor such as a metal strip is immersed in a suitable ionic solution, such as a solution of its own ions, a potential difference (voltage) is created between the conductor and the solution. This system constitutes a half-cell or electrode (Fig. 15.1). The metal strip in the solution is called an electrode and the ionic solution is called an electrolyte. We use the term electrode to mean both the solid electrical conductor in a half-cell (e.g., the metal strip) and the complete half-cell in many cases, for example, the standard hydrogen electrode, the calomel electrode. Each half-cell has its own characteristic potential difference or electrode potential. The electrode potential measures the ability of the half-cell to do work, or the driving force for the half-cell reaction. The reaction between the metal strip and the ionic solution can be represented as...
