第4节 反应机理所谓基元反应是指反应物分子一步直接转化为产物的反应。 如:NO2+CO=NO+CO2反应物NO2分子和CO分子经过一次碰撞就转变成为产物NO分子和CO2。 .ppt,第 4 节 反应机理;Elementary reactions are steps of molecular events showing how reactions proceed. T
The paper studies the transfer of the oxygen atom O from the NO2 molecule to the CO molecule, resulting in the formation of CO2. The methods of quantum mechanics are used to obtain transition states, vibrational frequencies and reaction paths CO + NO2 <-> CO2 + NO, and their key energy...
Synergistic Effect between NO2 and SO2 in Their Adsorption and Reaction on γ-Alumina Field measurements showed that there exists a correlation between nitrate and sulfate on mineral dust. In this work, the synergistic mechanism of adsorption and reaction between SO2 and NO2 on gamma-alumina was ...
These new species proceed to form the products,HONO+CO2andHNO2+CO2. Reaction channels leading to the formation of CO are energetically noncompetitive with those yieldingCO2. The lower energy pathways produceHONO+CO2representing new mechanisms for the formation of HONO, through an exchange of carbon...

/CO2 collisions over the centre-of-mass energies from near-thermal to 6?eV. Two different channels of the reaction were studied. Under the thermal conditions of the VT-SIFT, the reaction is seen to proceed slowly via ternary association ultimately producing CO3– ions, the measured effective ...
