For the following reactions,

Question:

For the following reactions, equilibrium constants are given :

$\mathrm{S}(\mathrm{s})+\mathrm{O}_{2}(\mathrm{~g}) \rightleftharpoons \mathrm{SO}_{2}(\mathrm{~g}) ; \mathrm{K}_{1}=10^{52}$

$2 \mathrm{~S}(\mathrm{~s})+3 \mathrm{O}_{2}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{SO}_{3}(\mathrm{~g}) ; \mathrm{K}_{2}=10^{129}$

The equilibrium constant for the reaction,

$2 \mathrm{SO}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{SO}_{3}(\mathrm{~g})$ is :

  1. $10^{181}$

  2. $10^{154}$

  3. $10^{25}$

  4. $10^{77}$
