90. The reaction of nitric oxide with hydrogen and with deuterium

Blind Search for Complex Chemical Pathways Using Harmonic Linear Discriminant Analysis

“…47 Theoretical modeling suggests the step HNO + NO −→ N 2 O + OH to be the rate-controlling one. It is also worth mentioning that, for calculating the reaction rate, the previous kinetic data by Hinshelwood and co-workers 48 suggesting that the reaction is third-order with…”

“…It is worth underlining that such a reaction step sequence agrees with both the mechanism hypothesized in 49 and the third-order expression of the reaction rate reported in. 48 As a second example, we choose a paradigmatic reaction that appears often in chemistry textbooks…”

Thermal reduction of NO by H2: Kinetic measurement and computer modeling of the HNO + NO reaction

“…Hinshelwood and co-workers [3,4] studied the reaction of NO with H2 by measuring the rates of total pressure change manometrically over a wide range of NO and Hz partial pressures at temperatures between 904 and 1099 K. The reaction was found to be approximately third-order, in accordance with the rate equation [Hz], which could be improved with the additional terms as described above for the rate of H2O production.…”

“…The points are experimental results of Hinshelwood [4] of reaction rates with respect to NO pressure and H2 pressure for with the set of radical reactions given in Table I. The reduction reaction, initiated by the metathetical reaction, H z + NO -HNO + H (l), was found to be controlled predominantly by the HNO + NO -N20 + OH reaction, (2), as was concluded by Normalized sensitivity coefficients for H2 corresponding to Hinshelwood's The values of kz, evaluated from four different sets of data obtained by totally different techniques-the FTIR spectrometric measurement of NO and C02 (this work), the gravimetric determination of H2O [51, the UV photometry of NO [61, and the manometric measurement of total pressure change [3,4], agree very closely with each other as is evident from Figure 5. The least-squares analysis of these data covering as many as 45 temperature points gives rise to the following expression: exp[(-14,890 ?…”

“…Παρόλα αυτά όμως, οι παραπάνω αντιδράσεις αποδείχτηκαν από κινητική άποψη πρακτικά αδύνατες[66]. Γι' αυτό το λόγο δεν απέκτησαν τεχνολογική σημασία και συνεπώς μελετήθηκαν σημαντικά λιγότερο από τις αντίστοιχες ετερογενείς αντιδράσεις.Σχετικά με το σύστημα Η2 + NO οι πρώτες εργασίες ανάγονται στις αρχές του αιώνα και έγιναν από τον Hinsheiwood[74]. Χρησιμοποιήθηκε στατική πειραματική διάταξη με έμμεση παρατήρηση της αντίδρασης μέσω των μεταβολών της πίεσης του συστήματος.…”
