The <Gibbs energy of activation> is the standard molar <Gibbs free energy> change associated with going from the starting <reactants> to the <transition state> in <transition state theory>. It specifies the directional barrier, rather than the overall endpoint change in <Gibbs free energy>. Use consistent <standard states> when comparing <Gibbs energies of activation> and <rate constants>. See the https://goldbook.iupac.org/terms/view/G02631[IUPAC Gold Book: Gibbs energy of activation].
