The reactions of O2+ with both cyclic molecules proceed via non-dissociative and dissociative charge transfer at the capture collision rate from 298 to 700 K. From 298 to 500 K, NO+ reacts with the two neutral reagents via non-dissociative hydride transfer, and from 500 to 700 K, ...
The interaction of soot with NO and O2 is investigated in order to analyze the capability of soot to interact with gas reactants. Soot samples formed at the highest temperatures are less reactive towards O2 and NO than those formed at lower temperatures. Soot samples appear to be more ...
The O-·(X2O)n≤5 and O2-·(X2O)n≤3 clusters were observed to react quite efficiently with NO, and the rate constants for these reactions were determined. The observed rate constants for O2-·(X2O)n show a positive temperature dependence. This observation is explained in terms of ...
A direct measurement of the CH3C(O)O2 + NO gas-phase reaction rate coefficient over the temperature range 200402 K was made using chemical ionization mass spectrometric detection of the CH3C(O)O2 reactant. A significant temperature dependence was observed, and a temperature dependent expression of...
There are NO2, NO, and O2 in a chamber at STP. This chamber is open at the bottom and is situated at the surface of a tank of water. Assuming all the gases in the chamber completely react with the H2O to form HNO2, what is the possible range of concentration c of the resulting ...
we find a complex formation mechanism, and at the medium temperature range the behavior is interpreted to be a consequence of the correlation of O + ( 4 S) and NO ( 2 Π) with the excited states 3 A 1 , 3 B 1 of NO 2 + , which lie slightly above the reactants in energy. At...

Rate coefficients and product ions have been determined for the NO + and O 2 + reactions with H 2O 2 molecules (H 3O + ions do not react at a measurable rate with H 2O 2 molecules) and for the rapid reactions of H 3O +, NO + and O 2 + with CH 3C(O)OOH molecules. It ...
