Explore the N2/NO/NO2 equilibrium in ambient atmosphere (P = 1 atm, T = 25 oC) after the oxides NO and NO2 have been produced by combustion at 2000 K. The relevant reactions are:
0.5N2 + 0.5O2 = NO
NO + 0.5O2 = NO2
Consider that the initial exhaust gas composition is a result of diesel fuel combustion in 30% excess air.

(a) Determine the equilibrium constants for these reactions.
(b) Determine the equilibrium mole fractions of NO and NO2. Comment on their change with respect to the exhaust gas composition at 2000 K.
