The equilibrium constant (KP) for the formation of the air pollutant nitric oxide (NO) in an automobile

Question:

The equilibrium constant (KP) for the formation of the air pollutant nitric oxide (NO) in an automobile engine at 530°C is 2.9 × 10-11:
The equilibrium constant (KP) for the formation of the air

(a) Calculate the partial pressure of NO under these conditions if the partial pressures of nitrogen and oxygen are 3.0 atm and 0.012 atm, respectively.
(b) Repeat the calculation for atmospheric conditions where the partial pressures of nitrogen and oxygen are 0.78 atm and 0.21 atm and the temperature is 25°C. (The KP for the reaction is 4.0 × 10-31 at this temperature.)
(c) Is the formation of NO endothermic or exothermic?
(d) What natural phenomenon promotes the formation of NO? Why?
