Why Are Different Catalysts Needed for Different Reactions?
Different reactions have distinct mechanisms and energy requirements, necessitating the use of specific catalysts tailored to each reaction. For example, acid-base catalysts are effective in reactions involving proton transfer, while transition metal catalysts are often used in redox reactions due to their ability to change oxidation states. The choice of catalyst can also influence the selectivity of the reaction, determining which products are formed. In the production of fine chemicals, where high selectivity is crucial, specially designed catalysts are often employed to ensure the desired product is obtained with minimal side products.
