Spin-inversion and spin-selection in the reactions FeO(+) + H2 and Fe(+) + N2O.
The reactions of FeO(+) with H2 and of Fe(+) with N2O were studied with respect to the production and reactivity of electronically excited (4)Fe(+) cations. The reaction of electronic ground state (6)FeO(+) with H2 was found to predominantly produce electronically excited (4)Fe(+) as opposed to electronic ground state (6)Fe(+) corresponding to a spin-allowed reaction. (4)Fe(+) was observed to r...
متن کاملReactions of Fe+ and FeO+ with C2H2, C2H4, and C2H6: temperature-dependent kinetics.
We present the first temperature-dependent rate constants and branching ratios for the reactions of Fe(+) and FeO(+) with C2H2, C2H4, and C2H6 from 170 to 700 K. Fe(+) is observed to react only by association with the three hydrocarbons, with temperature dependencies of T(-2) to T(-3). FeO(+) reacts with C2H2 and C2H4 at the collision rate over the temperature range, and their respective produc...
متن کاملIron cation catalyzed reduction of N2O by CO: gas-phase temperature dependent kinetics.
The ion-molecule reactions Fe(+) + N2O → FeO(+) + N2 and FeO(+) + CO → Fe(+) + CO2, which catalyze the reaction CO + N2O → CO2 + N2, have been studied over the temperature range 120-700 K using a variable temperature selected ion flow tube apparatus. Values of the rate constants for the former two reactions were experimentally derived as k2 (10(-11) cm(3) s(-1)) = 2.0(±0.3) (T/300)(-1.5(±0.2)) ...
متن کاملFurther insight into the reaction FeO(+) + H2 → Fe(+) + H2O: temperature dependent kinetics, isotope effects, and statistical modeling.
The reactions of FeO(+) with H2, D2, and HD were studied in detail from 170 to 670 K by employing a variable temperature selected ion flow tube apparatus. High level electronic structure calculations were performed and compared to previous theoretical treatments. Statistical modeling of the temperature and isotope dependent rate constants was found to reproduce all data, suggesting the reaction...
متن کاملCORE FORMATION AND THE Fe/FeO RATIO OF THE EARTH, MARS AND VESTA: CONSTRAINTS
Introduction: It is generally assumed that the abundances of the siderophile elements in the terrestrial planet’s mantle are the result of core formation. High pressure experimental metal–silicate partitioning data for Ni, Co, V, Cr, Nb, Mn and Mo etc. were used to investigate the geochemical consequences of a range of models for core formation on Earth and the most popular model is a “deep mag...
