It is demonstrated that temperature jumps result from the chopped excitation, which drive the response of the system. A kinetic model is established to semi-quantitatively detail the role of the chemical equilibrium to that response.M. van Roozendael and M. HermanChemical Physics...
Infrared absorptions of N2O4(ν9) at CO laser frequencies were monitored as an NO2/N2O4 sample was subjected to visible radiation from an argon laser. Double resonance signals corresponding to a two-molecule scheme involving the 2NO2 ⇌ N2O4 chemical equilibrium have been observed and interprete...
Liquid NITROGEN TETROXIDE is an oxidizing agent consisting of an equilibrium mixture of colorless dinitrogen tetraoxide (N2O4) and red-brown nitrogen dioxide (NO2). The exact composition of the mixture depends on the temperature with higher temperature favoring conversion to NO2. Vaporizes readily to...
If a system releases 17 kJ of energy, and the surroundings do 47 kJ of work on the system, calculate the change in internal energy of the system in kJ.Which of the following systems at constant room temperature and pressure ...
向铁铜合金中加入过量的硝酸溶液,得到NO2、N2O4、NO混合气体,向反应后溶液中加入2mol/LNaOH溶液,至沉淀恰好完全.若将得到的NO2、N2O4、NO混合气体,与2.24L(标准状况下)O2混合后通入水中恰好被完全吸收生成硝酸.则反应中消耗的NaOH溶液的体积是( )A.150mlB.180m
Laboratory-scale measurements were performed on the absorption of NO2 gas into diluted nitric acid. The concentration of NO2 gas, which represents an NO2/N2O4 equilibrium, varied from 1000 to 20000 ppm, the carrier gas being nitrogen. The concentration of nitric acid ranged from 15 to 60 ...

Equilibrium mixtures of NO 2 and N 2 O 4 at (224 ± 2) K were perturbed by flash photolysis of a fraction of the N 2 O 4 . The rate of relaxation back to equilibrium was monitored by observing the transmittance of the 14P(11) line from a cw CO laser selected to coincide with ...
Vapour–liquid equilibriumA new thermodynamic model is presented, capable of accurately representing the vapour–liquid equilibrium pressures and densities, and liquid phase densities and enthalpies of dissociating dinitrogen tetroxide (N2O42NO2). The model is based on the Peng-Robinson equation of state...
