Preferred Label : activation energy;
Detailed label : activation energy (Arrhenius activation energy);
IUPAC definition : An empirical parameter characterizing the exponential temperature dependence of the
rate coefficient, k, Ea RT 2.(d(lnk)/dT), where R is the gas constant and T the
thermodynamic temperature. The term is also used for threshold energies in electronic
potential surfaces, in which case the term requires careful definition.;
