Question

The equilibrium constant of the following are :
N₂ + 3H₂ $â‡Œ$ 2NH₃Â Â Â Â Â Â Â Â Â Â Â Â K₁
N₂ + O₂ $â‡Œ$ 2NOÂ Â Â Â Â Â Â Â Â Â Â Â Â Â K₂
H₂ + $\frac{1}{2} O_{2} â†’ H_{2} O$ Â Â Â Â Â Â Â Â Â K₃
The equilibrium constant (K) of the reaction :
2NH₃ + $\frac{5}{2} O_{2} \overset{K}{â‡Œ}$ 2NO + 3H₂O, will be :

Accepted Answer

N2 + 3H2 â‡Œ 2NH3Â Â Â Â K1 â†’ (1) N2 + O2 â‡Œ 2NO Â Â Â Â K2 â†’ (2) H2 + 12O2â†’H2OÂ Â K3 â†’ (3) For reaction 2NH3 + 52O2â‡ŒK2NO + 3H2O â†’ (4) equation (4) = equation(2) + 3 Ã— equation(3) - equation(1) â‡’Â K=K2K33K1, Option (1)
