Anderson Arrhenius

Quite different from that, Omerzu et al. proposed that TDAE-C60 is an Anderson-type insulator where the disorder is due to the orientational disorder °f C60 molecules [95]. This has been concluded from the thermally activated type of the conductivity, which in the temperature range between 100 and 300 K follows an Arrhenius law...

The calculations show that the substitutional Ru should be active for CH3OH dissociation. As mentioned earlier experimentally methanol does not bind at Ru because the sites are preferentially covered by H2O and OH. The Ru atoms in the surface provide nucleation sites only for OHgds formation. Like pure RUio, substituted Ru shows smaller and E for H2O dissociation than does Pt. The calculated D,. hc of H2O on (Pt3)(Pt4Ru3) is 0.31 eV, 0.5 eV less endothermic than on pure Pt (Fig. 6). The activation energy for H2O dissociation on (Pt3)(Pt4Ru3) is also smaller by 0.18 eV than on pure Pt, in agreement with earlier work of Anderson et al. [86]. Assuming that the pre-exponential factors A in the Arrhenius equation, k=A exp(-E /RT), are approximately the same for both pure Pt and mixed Pt-Ru clusters, a decrease of 0.18 eV in E would increase the rate of H2O dissociation reaction by a factor of 1000. 

Anderson made further studies on precipitated- and fused-iron catalysts to determine the relationship between rate and operating temperature. Tests were made with varying temperatures and flows at a constant conversion of 1 Hi ICO synthesis gas. Arrhenius plots of space-time yield [voliume of Hi -f- CO converted/ (volume of catalyst) (hour)] against reciprocal of the absolute temperature were approximately linear. The over-all apparent activation energy was 20.0-20.9 kcal/g mole, and a general expression was established to include temperature... 

This is copiously documented by references to literature, some of which are incorrect. In 1887 he became professor of physical chemistry in Leipzig, a post which had been founded in 1871, and in the same year he began the publication of the Zeitschrift fur physikalische Chemie, in association with van t Hoff and Arrhenius (whom he met in Uppsala in 1884). One of the first (in 1879) to appreciate the importance of Ostwald s researches on the law of mass action was Matthew Moncrieff Pattison Muir (Glasgow, i November 1848-Epsom, 2 September 1931), demonstrator in Anderson s College,...
