Q. For the equilibrium $2NOBr(g) \rightleftharpoons 2NO(g) + Br_{2}(g)$, calculate the ratio $\frac {K_{P}}{P}$, where $P$ is the total pressure and $P_{Br_{2}}= \frac {P}{9}$

Equilibrium

Solution:

$P_{T} =\frac{6P}{9} +\frac {2P}{9} =\frac {P}{9} =P$
$K_{p}=\frac{\left(\frac{2P}{9}\right)^{2}\times\left(\frac{p}{9}\right)}{\left(\frac{6p}{9}\right)^{2}}=\frac{Kp}{P}=\frac{1}{81}$
