Abstract : The thermodynamic properties of air equilibrium are obtained by the methods of statistical thermodynamics. The species assumed possible in this model are N2, O2, NO, N, O, N+, O+, NO+ and e- electrons. These nine species constitute the major components of air and give results in very close agreement with much more elaborate models. The two independent variables are density and temperature. The FORTRAN program for the IBM 7090 digital computer is presented, also tables and graphs of the thermodynamic properties (covering a wide range of temperatures and densities) are indluded for completeness.
