    Rate of adsorption to and desorption from a langmuir surface: The case of zero activation barrier to adsorption without dissociation (1990)
    Springer
    Catalysis letters 6 (1990), S. 317-320 
    Details
    ISSN: 1572-879X
    Keywords: Desorption from a Langmuir surface ; pre-exponential factor for desorption rate constant
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Many rate constants of elementary steps on single crystals have been measured. Their pre-exponential factors can now be compared to those calculated by transition state theory. Such a calculation is presented in this Letter with due attention to microscopic reversibility, standard states, and configurational entropy.

    Description / Table of Contents: Abstract Влияние малых (ниже 0,02) молярных фракций воды на скорость разложения аммиака на платиновой проволоке исследовали при давлениях аммиака, изменяющихся в интервале от 6,7 до 93,3 кПа, и температурах от 800 до 1700 K. Присутствие воды сильно ингибирует скорость реакции во всех экспериментах.
    Notes: Abstract The influence of small (lower than 0.02) molar fractions of water on the rate of ammonia decomposition on platinum wires was studied for ammonia pressures varying between 6.7 and 93.3 kPa and temperatures between 800 and 1700 K. The presence of water strongly inhibited the rate of reaction in all experiments.

    Description / Table of Contents: Abstract Измерена скорость разложения аммония на поликристаллической проволоке Rh в интервале температур 600–1800 K и при давлениях 13,3 Па−103 кПа. Она описывается уравиением скорости мономолекулярной реакции, типа Лаигмюра-Хиншельвуда. При высоких температурах и давлениях скорость реакции лимитируется переносом массы.
    Notes: Abstract The rates of ammonia decomposition on polycrystalline Rh wires between 600 and 1800 K and at pressures between 13.3 Pa and 103 kPa were measured and fitted with a Langmuir-Hinshelwood unimolecular reaction rate expression. At high temperatures and pressures the reaction seems to be mass transfer controlled.

    Description / Table of Contents: Abstract Скорость распада HCOOH на поликристаллическом вольфраме проверялась в широком интервале температур катализатора (600〈T〈1800 К) для давлений между 0,1 и 100 торр. Данные для низкого давления (p≤3 торр) могут быть описаны уравнением Лангмюра-Хиншельвуда для скорости мономолекулярной реакции; при более высоких давлениях реакция становится контролируемой передачей массы.
    Notes: Abstract The rates of HCOOH decomposition on polycrystalline tungsten are examined over a wide range of catalyst temperatures (600〈T〈1800 K) at pressures between 0.1 and 100 Torr. Low pressure (p≤3 Torr) data can be fitted by a Langmuir-Hinshelwood unimolecular rate expression; at higher pressures the reaction becomes mass transfer controlled.

    Notes: Abstract The oxidation of methane on supported chromia was studied at temperatures varying between 423 and 743 K and CH4/O2 ratios between 1 and 9 in a differential reactor. The main reaction products observed were carbon monoxide and formaldehyde. The rates of reaction obey a power law expression.

    Description / Table of Contents: Abstract Разложение метана на вольфрамовой проволоке было изучено при атмосферном давлении и в интервале температур 1700–2000 К. Измеряли вероятности реакции и скорости диффузии углерода в массу вольфрама. Согласие с данными других авторов указывает, что вероятность реакции остается постоянной при ири изменениях давлений метана, превышающих величину 106.
    Notes: Abstract Methane decomposition on tungsten wires is studied at atmospheric pressure and temperatures between 1700 and 2000 K. Reaction probabilities on the carbonized surface are measured along with diffusion coefficients of carbon into bulk tungsten. Agreement with other authors' data indicate that the reaction probability remains constant for changes over 6 orders of magnitude in the methane pressure.

    Description / Table of Contents: Abstract Измерена кинетика разложения аммиака на поликристаллической Pt в интервале температур 600–1700 К и при давлениях от 1,3 до 93 кПа, которая подчиняется уравнению Пангмюра-Хиншельвуда для скорости мономолекулярной реакции. Это уравнение скорости, как уже ранее установлено, соответствует данным в том же интервале температур, но для давлений от 2 до 1400 Па.
    Notes: Abstract The kinetics of ammonia decomposition on polycrystalline Pt at temperatures between 600 and 1700 K and at pressures between 1.3 and 93 kPa were measured and correlated with a Langmuir-Hinshelwood unimolecular reaction rate expression. This rate expression had previously been shown to fit data in the same temperature range for pressures between 2 and 1400 Pa.

    Notes: Abstract The rates of ammonia decomposition on polycrystalline Ir and Pd wires were measured at temperatures between 900 and 2000 K and at pressures between 50 and 770 Torr. Rates on Ir were fitted with a Langmuir-Hinshelwood unimolecular reaction rate expression. Rates on Pd could not be fitted with a rate expression, although activation energies were obtained.
