Q. When sulphur is heated at $800 K$ , there exists on equilibrium $S_{8} (g) ⇌ 4 S_{2} (g)$ . The initial pressure of $1$ atm. falls by $20%$ at equilibrium. Find the value of $K_{P}$ for the referred reaction

$0.512 a t m^{3}$

$2.50 a t m^{3}$

$1.20 a t m^{3}$

$3.24 a t m^{3}$

$K_{P} = \frac{p _{S_{2}}^{4}}{p _{S_{8}}} = \frac{( 0.8 ) ^{4}}{( 0.8 )} = (0.8)^{3} a t m^{3}$
$= 0.512 a t m^{3}$
