`H_(2)(g) + CO_(2)(g) ltimplies H_(2)O(g) + CO(g)` का 1395K पर साम्य सिथरांक ज्ञात करो यदि 1395K पर-
`2H_(2)O(g) ltimplies 2H_(2)(g) + O_(2)(g), K_(1)=2.1 xx 10^(-13)`
`2CO_(2)(g) ltimplies 2CO(g) + O_(2)(g), K_(2)=1.4 xx 10^(-12)`

Explanation

`2H_(2)O(g) ltimplies 2H_(2)(g) + O_(2)(g)` के लिए,
`K_(1) = ([H_(2)]^(2)[O_(2)])/([H_(2)O]^(2))`…………(1)
`2CO_(2)(g) ltimplies 2CO(g) + O_(2)(g)` के लिए,
`K_(2) = ([CO]^(2)[O_(2)])/([CO_(2)]`……….(2)
`H_(2)(g) + CO_(2)(g) ltimplies H_(2)O(g) + CO_(g)` के लिए,
`H_(2)(g) + CO_(2)(g) ltimplies H_(2)O(g) + CO(g)` के लिए,
`K=([H_(2)O][CO])/([H_(2)][CO_(2)])`............(3)
समीकरण (2) को समीकरण (1) से विभाजित करने पर,
`K_(2)/K_(1)=([CO_(2)]^(2)[O_(2)])/([CO_(2)]^(2)) xx [H_(2)]^(2)/([H_(2)]^(2)[O_(2)]) = ([CO]^(2)[H_(2)O]^(2))/([CO_(2)]^(2)[H_(2)]^(2))=K^(2)`
`K=sqrt([K_(2)/K_(1)]) = sqrt([(1.4 xx 10^(-12))/(2.1 xx 10^(-13))])=2.58`
