The equilibrium constant (K_C) for the reaction N₂(g) + O₂(g)

\to

2NO(g) at temperature T is 4

\times

10^–4. The value of K_C for the reaction, NO(g)

\to

1/2N₂(g) + 1/2O₂(g) at the same temperature is :

Accepted Answer

For the reaction

N_{2} + O_{2} \to 2 N O

K = 4 \times 10^{- 4}

Hence for the reaction

N O \to \frac{1}{2} N_{2} + \frac{1}{2} O_{2}

K^{'} = \frac{1}{\sqrt{K}}

= \frac{1}{\sqrt{4 \times 10^{- 4}}}

= 50
