The equilibrium constant (Kp) for the formation of the air pollutant nitric oxide (NO) in an automobile engine at 530 degree C is 2.9 x 10 to the minus eleventh

N2(g) + O2 (g) = 2 NO (g)

What is the partial pressure of NO under these conditions if the partial pressures of nitrogen and oxygen are 3.0 atm and 0.013 atm, respectively ?

What is it for atmospheric conditions where the partial pressures of nitrogen and oxygen are 0.78 atm and 0.18 atm and the temperature is 25 degrees C ?( Kp= 4.0 x 10 to the minus 31 at this temperature)

Is the formation of NO endothermic or exothermic?
