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

Explanation

(i) `K_( c)=([NO]^(2)[Cl_(2)])/([NOCl]^(2))`
(ii) `K_( c) = [NO_(2)]^(4)[O_(2)] [therefore [CuO(s)]-[Cu(NO_(3))_(2)(s)]=1]`
(iii) `K_( c) = ([CH_(3)COOH][C_(2)H_(5)OH])/([CH_(3)COOC_(2)H_(5)][H_(2)O])`
(iv) `K_( c)=1/([Fe^(3+)][OH^(-)]^(3)) [therefore [Fe(OH)_(3)(s)]=1`
(iv) `K_( c)=1/([Fe^(3+)][OH^(-)]^(3)) [therefore [Fe(OH)_(3)(s)=1]`
(v) `K_( c)=([IF_(5)]^(2))/([F_(2)]^(5)) [therefore [I_(2)(s)]=1]`
