Unit Objectives Electrochemistry Electrochemistr ochemistr y 3. After studying this Unit, you will be able to describe an electrochemical cell and differentiate between galvanic Chemical reactions can be used to produce electrical energy, conversely, electrical energy can be used to carry out chemical and electrolytic cells;. reactions that do not proceed spontaneously. apply Nernst equation for calculating the emf of galvanic cell and define standard potential of the cell; Electrochemistry is the study of production of derive relation between standard electricity from energy released during spontaneous potential of the cell, Gibbs energy chemical reactions and the use of electrical energy of cell reaction and its equilibrium to bring about non-spontaneous chemical constant; transformations.
during the redox reaction Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s) (3.1) to electrical energy and has an electrical potential equal to 1.1 V when concentration of Zn2+ and Cu2+ ions is unity (1 mol dm–3)*. Such a device is called a galvanic or a voltaic cell. If an external opposite potential is applied in the galvanic cell [Fig. 3.2(a)] and ...
