Purpose of a catalyst
WebDec 25, 2015 · Without this enhanced electrophilicity, the activation energy for nucleophilic attack would be much higher, and the rate of reaction would be much slower. Hence, the sulfuric acid is acting as a catalyst for the reaction: it provides an alternate pathway that has a lower activation energy. Answer link. WebMar 20, 2024 · Carboxylic acids (R-COOH, where the R is an organic attachment) may be too weak to use, unaided, for an esterification reaction. A strong proton donor is needed to make the carboxylic acid act as if it were, of itself, a good proton source. Sulfuric acid in esterification accomplishes the task by injecting a proton into the carboxylic acid …
