Consider the reaction N 2 (g) + 3H 2 (g) 2NH 3 (g) The equilibrium constant of the above reaction is K p . If pure ammonia is left to dissociate, the partial pressure of ammonia at equilibrium is given by (Assume that 3 NH P << P total at equilibrium)

1. 4 P K 3 2 2 1 2 3
2. 4 P K 2 P 2 1
3. 16 P K 3 2 P 2 3 2 1
4. 16 P K 2 P 2 1

Correct answer: 16 P K 3 2 P 2 3 2 1
