2SO2 (g) + O2 (g)→2SO3 (g) Keq = ([SO3]2/[O2][SO2]2) = (K2/K1) = (10129/10104) = 1025

Q. For the following reactions, equilibrium constants are given :
$S (s) + O_{2} (g)$ $⇌$ $S O_{2} (g); K_{1} = 1 0^{52}$ $2 S (s) + 3 O_{2} (g)$ $⇌$ $2 S O_{3} (g); K_{2} = 1 0^{129}$
The eqilibrium constant for the reaction,
$2 S O_{2} (g) + O_{2} (g)$ $⇌$ $2 S O_{3} (g)$ is :

10 $^{181}$

10 $^{154}$

10 $^{25}$

10 $^{77}$

$2 S O_{2} (g) + O_{2} (g) \to 2 S O_{3} (g)$
$K_{e q} = \frac{[ S O _{3} ] ^{2}}{[ O _{2} ] [ S O _{2} ] ^{2}}$
$= \frac{K _{2}}{K _{1}} = \frac{1 0 ^{129}}{1 0 ^{104}} = 1 0^{25}$
