Chemistry - Chemical Equilibrium Question with Solution | TestHub

Reaction Equilibrium Constant:

$\frac{1}{2}{N}_2(g)+\frac{1}{2}{O}_2(g)\rightleftharpoons N{O}_2(g)$ $K_1$

$2N{O}_2(g)\rightleftharpoons N_2{O}_4(g)$ $K_2$

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

$N_2{O}_4(g)\rightleftharpoons N_2(g)+\frac{1}{2}{O}_2(g)$
