What Mechanisms are Involved in Catalytic Reactions?
The mechanisms of catalytic reactions can vary significantly based on the nature of the catalyst and the reaction. Common mechanisms include: - Adsorption of Reactants: In heterogeneous catalysis, reactants adsorb onto the surface of the catalyst, where they are more likely to collide and react. - Formation of Transition States: Catalysts stabilize the transition state of the reaction, thereby reducing the activation energy. - Desorption of Products: Once the reaction has occurred, the products desorb from the catalyst surface, freeing it to catalyze another reaction cycle.
