Enthalpy–entropy compensation

In thermodynamics, enthalpy–entropy compensation is a specific example of the compensation effect. The compensation effect refers to the behavior of a series of closely related chemical reactions (e.g., reactants in different solvents or reactants differing only in a single substituent), which exhibit a linear relationship between one of the following kinetic or thermodynamic parameters for describing the reactions: Between the logarithm of the pre-exponential factors (or prefactors) and the activation energies ln ⁡ A i = α + E a , i R β {\displaystyle \ln A_{i}=\alpha +{\frac {E_{{\text{a}},i}}{R\beta }}} where the series of closely related reactions are indicated by the index i, Ai are the preexponential factors, Ea,i are the activation energies, R is the gas constant, and α, β are constants.
