Write the expressions for equilbrium constant `K_(c)` and `K_(P)` and classify in Homogeneous and Hetereogeneous equilbrium:
(i) `N_(2)O_(4)(g)hArr2NO_(2)(g)`
(ii) `3Fe(S)+4H_(2)O(g)hArrFe_(3)O_(4)(S)+4H_(2)(g)`
(iii) `NH_(4)HS(S)hArrNH_(3)(g)+H_(2)S(g)`
(iv) ` CH_(3)COOH(f)+C_(2)H_(5)OH(f)hArrCH_(3)COOC_(2)H_(5)(f)+H_(2)O(f)`
(V) `MgCO_(3)(S)hArrMgO(S)+CO_(2))g)`
(vi) `2H_(2)S(g)hArr2H_(2)S(g)hArr2H_(2)(g)+S_(2)(g)`
(vii) `SO_(2)(g)+NO_(2)(g)+NO_(2)(g)hArrSO_(3)(g)+NO(g)`
(viii) ` NH_(4)NO_(2)(S)hArrN_(2)(g)+2H_(2)O(f)`

Answer

(i) Homogeneous equilibrium `K_(C)=([NO_(2)]^(2))/([N_(2)O_(4)]) K_(P)=((P_NO_(2)^(2)))/((P_(N_2O_4)))`
(ii) Hetereogeneous equilibrium `K_(C)=([H_(2)^(4))/([H_(2)O]) K_(P)=(P_(H_2))^(4))/((P_(H_2O)^(4))`
(iii) Hetereogeneous equilibrium `K_(C)=[NH_(3)] [H_(2)S] K_(P)=(P_(NH_(3))(P_(H_(2S))`
(iv) Homogeneous equilibrium
`K_(C)=([CH_(3)COOC_(2)H_(5)][H_(2)O])/([CH_(3)COOH] [C_(2)H_(5)OH])` But K_`(P)` is not define for liquid system
(v) Hetereogeneous equilibrium `K_(C)=[CO_(2)] K_(P)=(P_(CO_2))
(vi) Homogeneous equilibrium ``K_(C)=([H_(2)]^(2)[S_(2)])/([H_(2)S]^(2)) K_(P)((P_(H_(2)))(P_(S_(2))))/((P_(H_(2)S)^(2))`
(vii) Homogeneous equilibrium `K_(C)=([SO_(3)][NO])/([SO_(2)][NO_(2)]) K_(P)((P_(SO_(3)))(P_(NO)))/((P_(SO_(2)))(P_(NO_(2)))`
Hetereogeneous equilibrium `K_(C)=[N_(2)] K_(P)=(P_N_(2))`
