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

` K_c= ( [CH_3COOH(aq) ][C_2H_5OH(aq) ])/([CH_3COOC_2H_5(aq) ][H_2O(l)]) `
