==== Unified equation ====
In an effort to unify the above described equations the Mayr equation is rewritten as:<ref name=Mayr2006 />
:''<math>\log(k) = s_Es_N(N + E)</math>''

with s<sub>E</sub> the electrophile-dependent slope parameter and s<sub>N</sub> the nucleophile-dependent slope parameter. This equation can be rewritten in several ways:
* with s<sub>E</sub> = 1 for carbocations this equation is equal to the original Mayr–Patz equation of 1994,
* with s<sub>N</sub> = 0.6 for most n nucleophiles the equation becomes
::<math>\log(k) = 0.6s_EN + 0.6s_EE</math>
:''or the original Scott–Swain equation written as:''
::<math>\log(k) = \log(k_0) + s_EN</math>
* with s<sub>E</sub> = 1 for carbocations and s<sub>N</sub> = 0.6 the equation becomes:
::<math>\log(k) = 0.6N + 0.6E</math>
:or the original Ritchie equation written as:
::<math>\log(k) - \log(k_0) = N^+</math>
