## Abstract Recently, we have discovered the unusual inverse temperature dependence of the kinetic isotope effect (KIE) for the OH + __c__βC~6~H~12~/__c__βC~6~D~12~ reaction in water. Temperature increase causes a KIE increase; this is valid for both the Fenton system (I) and the HOONOο£ΏH~2~O system
Rates of oxidation of XCOO-(X = H, D) by Brz in acid aqueous media were measured between 274 and 332 K. The derived Arrhenius parameters for both reactions log k ~( M -l S-') = (11.81 f 0.10) -(14.33 f 0.13)/0 log ~D ( M -' S-') = (13.77 f 0.13) -(17.62 f 0.04)/0 where 0 = 4.575T X kcal/mol, with (
We experimentally studied the influence of temperature and sulfur loading on the axial distribution of reactions inside a commercial lean NO x trap (LNT) catalyst to better understand the global performance trends. Our measurements were made on a monolith core, bench-flow reactor under cycling condi
