Catalysts speed up the rate of a chemical reaction without being consumed in the process. They provide an alternative pathway for the reaction with a lower activation energy, making it easier for the reactants to form products.
Examples of catalysts:
* Enzymes: Biological catalysts that speed up biochemical reactions in living organisms.
* Metal catalysts: Used in many industrial processes, such as the production of gasoline and plastics.
* Acid catalysts: Used in many organic reactions, such as esterification and dehydration.
Key characteristics of catalysts:
* They are not consumed in the reaction.
* They lower the activation energy of the reaction.
* They speed up the rate of the reaction.
* They do not affect the equilibrium position of the reaction.
