a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
a person or thing that precipitates an event.
Heat or raise the concentration of the reactants, or add a catylast.
Sulphuric acid is used as a catalyst in esterification reactions to increase the rate of the reaction by providing protons that can assist in forming the ester product. It helps in protonating the carbonyl oxygen of the carboxylic acid, making it more susceptible to nucleophilic attack by the alcohol.
