Thermodynamic and Transport Properties for the N2O4 yields 2NO2 yields 2NO+O2 (reversible reaction) System
Abstract
Thermodynamic and transport properties, including enthalpy, entropy, heat capacity, molecular weight, viscosity, and thermal conductivity, have been calculated for the N2O4 = 2NO2 equilibrium and also the N2O4 = 2NO2 = 2NO+O2 equilibrium from 300 to 1280 K and from 0.Ol to 100 atmospheres. The Prandtl number, Lewis number, isentropic exponent, and two derivatives involving the molecular weight, pressure, and temperature were also calculated. The Chapman-Enskog theory of monatomic gases was applied in the transport property calculations, with an Eucken-type correction to the thermal conductivity to account for internal degrees of freedom. An expression for the thermal conductivity due to chemical reaction was also included. The transport cross sections were calculated for the Lennard-Jones (12-6) potential, the parameters being obtained from analysis of experimental viscosity and thermal conductivity data. Also included in the calculations is a parameter, which may be useful in analyzing to what extent chemical reaction in the gas phase affects thermal conduction. This parameter is tabulated over the same pressure and temperature range over which the thermodynamic and transport properties were calculated.
