The visible Chemiluminescence of the NO + O 3 → NO 2 * + O 2 reaction has been studied as a function of collision energy using a supersonic molecular beam of NO. The reaction threshold E 0 = 3.00 ± 0.45 kcal/mol is found to lie significantly below the Arrhenius activation energy of E a = 4.18 ± 0.3 kcal/mol. This clearly demonstrates the basic difference between the two quantities.
