K1=([. N O2 ]./[. N2 ].1 / 2 [. O2 ].) â¦(i) K2=([. N2 O4 ]./[. N O2 ].2) â¦(ii) K=([. N2 ]. [. O2 ].2/[. N2 O4 ].) â¦(iii) Considering equation (i), (ii) and (iii) K=(1/K12 K2) .

Q. Consider the reactions

$\frac{1}{2} N_{2} + O_{2} ⇌ N O_{2}$ $K_{1}$

$2 N O_{2} ⇌ N_{2} O_{4}$ $K_{2}$

Using above equations, write down expression for K of the following reaction

$N_{2} O_{4} ⇌ N_{2} + 2 O_{2}$ K

$K_{1} K_{2}$

$\frac{K _{2}^{2}}{K _{1}}$

$\frac{1}{K _{1} K _{2}^{2}}$

$\frac{1}{K _{1}^{2} K _{2}}$

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

$K_{2} = \frac{[ N _{2} O _{4} ]}{[ N O _{2} ] ^{2}}$ …(ii)

$K = \frac{[ N _{2} ] [ O _{2} ] ^{2}}{[ N _{2} O _{4} ]}$ …(iii)

Considering equation (i), (ii) and (iii)

$K = \frac{1}{K _{1}^{2} K _{2}}$ .
