Kinetics and Reaction Pathways

Chemical kinetics, the study of reaction rates, includes a broad range of procedures, evaluations, and computations. You might be wondering why anybody would bother with this, but it turns out that we can use kinetic data to learn more about a reaction than simply how quickly it proceeds. We can learn about the reaction's mechanism, or the path it follows from reactants to products. It is obvious that there must be a continuous channel between reactants and products when you consider a reaction from a molecular perspective. In most reactions, just one or two bonds are broken and generated as the reaction progresses; the reactants do not suddenly vanish and then reappearance as products. The sequence in which bonds are broken and created, as well as the intermediate species involved, are indicated by this process or mechanism. However, we must rely on deductive techniques to understand what is happening because we cannot directly observe what occurs at the molecular level during a reaction. Some species in reaction pathways may only be present for femto (1015) or atto (1018) seconds, even when utilising advanced spectroscopic methods, which are covered in greater depth in the spectroscopy section. These events are challenging to analyse, and much of the most cutting-edge work being done today in physics and chemistry is focused on identifying and describing these fleeting molecular-level occurrences.
