Q. A vessel of one litre capacity containing $1$ mole of $S O_{3}$ is heated till a state of equilibrium is attained.
$2 S O_{3 (g)} ⇌ 2 S O_{2 (g)} + O_{2 (g)}$
At equilibrium, $0.6 m o l es$ of $S O_{2}$ had formed. The value of equilibrium constant is

0.18

0.36

0.45

0.68

$\Rightarrow$ Equilibrium constant is given by :
$K = \frac{[ S O _{2} ] ^{2} [ O _{2} ]}{[ S O _{3} ] ^{2}} = \frac{( 0.6 ) ^{2} ( 0.3 )}{( 0.4 ) ^{2}}$
$= 0.675 = 0.68$
