Q. For the equilibrium $2 NOB r (g) ⇌ 2 NO (g) + B r_{2} (g)$ , calculate the ratio $\frac{K _{P}}{P}$ , where $P$ is the total pressure and $P_{B r_{2}} = \frac{P}{9}$

$\frac{1}{9}$

$\frac{1}{81}$

$\frac{1}{27}$

$\frac{1}{3}$

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