A Review on Model Systems in Catalysis

Exploring the Role and Limitations of Catalysts in Organic Chemistry Reactions

Abstract

Throughout organic chemistry, catalysis plays an important role. Both the functional group kind the product utility classification identify the chemical agents listed in the section. Catalysis is the rise in chemical reaction rate by applying the catalyst to a reagent that is not absorbed by itself. The catalyst works by opening a route with lower activation barrier than uncatalyzed cycle among starting material product. Catalysis is a process through which small quantities of foreign substances termed catalysts, accelerate chemical reactions. An effective catalyst may increase rate of thermodynamically feasible reaction but cannot change thermodynamic equilibrium location. Although most catalysts are solids or liquids, they can also be gases. A cyclic cycle is the catalytic reaction. The reactant or reactants form a complex with the catalyst according to a simplified model, thereby opening up a path for their conversion into the product or products. The catalyst is then released and the next process will continue. Nevertheless, there is no eternal life for catalysts. Side reaction products or alter in catalyst structure result in deactivation of the catalyst.
