Ammonia and oxygen react to form nitrogen monoxide and water, like this:

4NH3

(g)

+

5O2

(g)

→

4NO

(g)

+

6H2O

(g)

Write the pressure equilibrium constant expression for this reaction.

4NH3+5O2 <=>4NO + 6H2O

Using the definition of Kp, we have
Kp=(Pno^4Ph2o^6)/(Pnh3^4Po2^5)
where Pno=partial pressure of NO, etc.

The numerical value for a given temperature can be evaluated when the actual partial pressures are known.
