NIST-JANAF table deltaG standard formation values at 5400 K for N(g), O(g) and NO(g) are 113.817 kJ/mol, -108.155 kJ/mol and 23.568 kJ/mol. Use a spreadsheet to calculate the composition of dry air at 5400K and 1 bar. Take the initial composition as .78 mol N2, .21 mol O2 and .01 mol Ar. Neglect the ionization of NO.
