निम्नलिखित अभिक्रियाओं के लिए साम्य सिथरांक का व्यंजक लिखिए-
(i) `KClO_(3)(s) <=> KCl(s) + 3/2O_(2)(g)`
(ii) `2CaC_(2)(s) + 5O_(2)(g) <=> 2CaCo_(3)(g) + 2CO_(2)(g)`
(iii) `2CO_(2)(g) <=> 2CO(g) + O_(2)(g)`
(iv) `Fe^(3+)(aq.) + SCN^(-) (aq.) <=> Fe(SCN)^(2+)(aq.)`

Explanation

(i) `K_(p) = (P_(O_(2)))^(3//2)`, (ii) `K_(p) = (P_(CO_(2)))^(2)/(P_(O_(2)))^(5)`
(iii) `K_(p) = ((P_(CO))^(2)(P_(O_(2))))/(P_(CO_(2))^(2)), K_(c) = ([CO]^(2)[O_(2)])/([CO_(2)]^(2))`
(iv) `K_( c) = ([Fe(SCN)^(2+)])/([Fe^(3+)][SCN^(-)])`
