Web7.3 Basics of Thermodynamics and Kinetics. You may recall from general chemistry that it is often convenient to describe chemical reactions with energy diagrams. In an energy diagram, the vertical axis represents the overall energy of the reactants, while the horizontal axis is the ‘ reaction coordinate ’, tracing from left to right the ... WebSimply explained, the process of electrolysis refers to decomposition of a given element under the influence of an electric current. The first electrolysis was carried out by Sir Humphrey Davey in the year 1808. This experiment revealed new understandings about the way certain elements behave and how they are different from compounds and ions.
