A) \[{{10}^{181}}\]
B) \[{{10}^{154}}\]
C) \[{{10}^{25}}\]
D) \[{{10}^{77}}\]
Correct Answer: C
Solution :
\[S(s)+{{O}_{2}}(g)\rightleftharpoons S{{O}_{2}}(g)\,\,\,\,\,\,\,{{K}_{1}}={{10}^{52}}\]?..(1) \[2S(s)+3{{O}_{2}}(g)\rightleftharpoons 2S{{O}_{3}}(g)\,\,\,\,\,\,{{K}_{2}}={{10}^{129}}\]?..(2) \[2S{{O}_{2}}(g)+{{O}_{2}}(g)\rightleftharpoons 2S{{O}_{3}}(g)\,\,\,\,\,\,{{K}_{3}}=x\] multiplying equation (1) by 2; \[2SO(s)+2{{O}_{2}}(g)\rightleftharpoons 2S{{O}_{2}}(g)\,\,\,\,\,\,K{{'}_{1}}={{10}^{104}}\] ...(3) \[\Rightarrow \]Substracting (3) from (2); we get \[2S{{O}_{2}}(g)+{{O}_{2}}(g)\rightleftharpoons 2S{{O}_{3}}(g);\] \[{{K}_{eq}}={{10}^{(129-104)}}={{10}^{25}}\]You need to login to perform this action.
