Consider the following gases equilibrium given below:
(i) N₂ + 3H₂ ⇔ 2NH₃, Eqm.Constant=K1
(ii) N₂ + O₂ ⇔ 2NO, Eqm.constant=K2
(III) H₂ + 12O₂ ⇔ H₂O, Eqm.constant=K3
The equilibrium constant for the reaction ,2NH₃ + 5/2O₂ ⇔ 3H₂O in terms of K1, K2 and K3 will be :
A.K1K2K3
B.K1K2/K3
C.K1K2/K2
D.K2K3/K1
