निम्नलिखित में से प्रत्येक अभिक्रिया के लिए साम्य स्थिरांक `K_(c)` का व्यंजक लिखिए-
`(i) 2NOCI_(g) → 2NO(g)+Cl_(2)(g)`
`(ii) 2Cu(NO_(3))_(2)(s)hArr 2CuO(s)+4NO_(2)(g)+O_(2)(g)`
`(iii) CH_(3)COOC_(2)H_(5)(aq)+H_(2)O(l)hArr CH_(3)COOH(aq)+C_(2)H_(5)OH)(aq)`
(iv) `Fe^(3+)(aq)+3OH^(-)(aq)hArr Fe(OH)_(3)(s)`
`(v) I_(2)(s)+5F_(2)hArr 2IF_(5)`

Explanation

`(i) K_(c)=([NO(g)]^(2)[CI_(2)(g)])/([NOCI(g)]^(2))`
`(ii) K_(c)=[NO(g)]^(4)[O_(2)(g)]{ :. [CuO(s]=[Cu(NO_(3))_(2)(s)]=1}`
`(ii) K_(c)=([CH_(3)COOH(aq][C_(2)H_(5)OH(aq)])`
`(iv) K_(c)=(1)/([Fe^(3+)(aq)][OH^(-)(aq)]^(3)) ( :.[ Fe(OH)_(3)(s)]=1)`
(v) `K_(c)=([IF_(5)]^(2))/([Fe_(2)]^(5)) ( :. [I_(2)(s)]=1)`
