Brønsted relation
Term · Chemistry · MLC-T-CHM-001513
A linear free-energy relationship that correlates the rate constant of a reaction with the acid or base strength of the catalyst. It describes how changes in the equilibrium constant for proton transfer affect the rate of proton-transfer reactions. The Brønsted exponent, derived from this relation, indicates the sensitivity of the reaction rate to catalyst strength.
