a) 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.
b) Vary the pressure over the range .001 bar to 1000 bar and plot the results(in other words, a graph of Pressure(x) versus the moles(y) of the different substances)
