Term: specific catalysis https://doi.org/10.1351/goldbook.S05796 Definition: The acceleration of a reaction by a unique catalyst, rather than by a family of related substances. The term is most commonly used in connection with specific hydrogen-ion or hydroxide-ion (lyonium ion or lyate ion) catalysis.
