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

Options:

Answer:

Solution:

$K_{1} = \frac{[N O_{2}]}{[N_{2}]^{1 / 2} [O_{2}]}$ …(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)
$K = \frac{1}{K_{1}^{2} K_{2}}$ .
