AN OUTLINE OF KINETICS VERSUS THERMODYNAMICS CHEMISTRY
Abstract: Nearly all chemical reactions has a kinetic and a thermodynamic feature. The terms ‘kinetic’ and ‘thermodynamic’ though inter-related are two diverse aspects of a chemical reaction. This paper represents an outline of the underlying relationships between the two through application to chemical reactions and an example from natural processes. A required condition for thermodynamic control is reversibility or a mechanism allowing the equilibration between products. In this manner, the thermodynamically …
