Write the expression for the equilibrium constant, `K_(c)` for each of the following reaction :
(i) `2NOCl (g) hArr 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)(aq)`
(iv) `Fe^(3+) (aq) + 3OH^(-) (aq) hArr Fe(OH)_(3)(g)`
(v) `I_(2)(s) + 5F_(2) hArr 2IF_(5)`

Explanation

(i) `K_(C)=([NO(g)]^(2)[Cl_(2)(g)])/([NOCl(g)]^(2))`
(ii) `K_(C)=[NO_(2)(g)]^(4)[O_(2)(g)]`
`K_(C)==([CH_(3)COOH(aq)][C_(2)H_(5)OH(aq)])/([CH_(3)COOC_(2)H_(5)(aq)][H_(2)O(l)])`
(iv) ` K_(C)=(1)/([Fe^(3+)(aq)[OH_(-)(aq)]_(3)])`
(v) `K_(C)=(1)/([F_(2)(g)]^(5))`
