Write the expression for the equilibrium constant `K_(c )` for each of the following reactions:
a. `2NOCl(g) hArr 2NO(g)+Cl_(2)(g)`
b. `2Cu(NO_(3))_(2)(s) hArr 2CuO(s)+4NO_(2)(g)+O_(2)(g)`
c. `CH_(3)COOC_(2)H_(5)(aq)+H_(2)O(1) hArr CH_(3)COOH(aq)+C_(2)H_(5)OH(aq)`
d. `Fe^(3+)(aq)+3OH^(Θ)(aq) hArr Fe(OH)_(3)(s)`
e. `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))`
