The
catalysis of a chemical reaction by a series of
Brønsted acids (which may include the solvated hydrogen ion) so that the rate of the catalysed part
of the reaction is given by
![∑ k HA [HA]](../../mathml/G02609-0.png)
multiplied by some function of
substrate concentrations. (The acids
HA
are unchanged by the overall reaction.) General
catalysis by acids can be experimentally distinguished from
specific catalysis by hydrogen cations (
hydrons) by observation of the
rate of reaction as a function of buffer concentration.
