Table II Reaction orders for QH2 (m) and surface (n) and rate constants (k) for semiquantitative comparison between each particle type by the method of initial rates. Errors reported are standard errors. SATEM normalized rate constant is denoted by kTEM, and SABET normalized rate constant is denoted by kBET.
