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

⇋

2NO(g) at temperature T is 4

\times

10^-4. The value of K_c for the reaction NO(g)

⇋

\frac{1}{2}

N₂ (g) +

\frac{1}{2}

O₂ (g) at the same temperature is :

Accepted Answer

K_{c} = \frac{{[N O]}^{2}}{[N_{2}] [O_{2}]} = 4 \times 10^{- 4}

K_{c}^{'} = \frac{{[N_{2}]}^{1 / 2} {[Q_{2}]}^{1 / 2}}{[N O]}

= \frac{1}{\sqrt{K_{c}}}

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

= 50
