Question

In the two gaseous reactions (i) and (ii) at $250^{\circ} C$
(i) $2 N O (g) + \frac{1}{2} O_{2} (g) \Leftrightarrow N O_{2} (g) K_{1}$
(ii) $2 N O_{2} (g) \Leftrightarrow 2 N O (g) + O_{2} (g), K_{2}$ the equilibrium constants $K_{1}$ and $K_{2}$ are releated as

K_{2} = \frac{1}{K _{1}}

K_{2} = K_{1}^{1 / 2}

K_{2} = \frac{K _{1}}{K _{1}^{2}}

K_{2} = K_{1}^{2}

For equation (i),

N O (g) \frac{1}{2} O_{2} (g) \Leftrightarrow N O_{2} (g)

K_{1} = \frac{[ N O _{2} ]}{[ N O ] [ O _{2} ] ^{1 / 2}}

....(i)
For reaction (ii)

2 N O_{2} (g) \Leftrightarrow 2 N O (g) + O_{2} (g) K_{2} = \frac{[ N O ] ^{2} [ O _{2} ]}{[ N O _{2} ] ^{2}}

.....(ii)
Now, on reversing equation (i), we get,

\frac{1}{k _{1}} = \frac{1}{\frac{[ N O _{2} ]}{[ N O ] [ O _{2} ] ^{1 / 2}}} = \frac{[ N O ] [ O _{2} ] ^{1 / 2}}{[ N O _{2} ] ^{2}}

(\frac{1}{K _{1}})^{2} = {\frac{[ N O ] [ O _{2} ] ^{1 / 2}}{[ N O _{2} ]}}^{2} = \frac{[ N O ] ^{2} [ O _{2} ]}{[ N O _{2} ] ^{2}} = K_{2}
