Write expression for the equilibrium con...

Write expression for the equilibrium constant, `K_(c)`, for each of the following reactions:
(i) `2NOCl_((g))harr2NO_((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(ag))+H_(2)O(I)hArr CH_(3)COOH_((aq))+C_(2)H_(5)OH_((aq))`
(iv) `Fe_((aq))^(+3)+3OH_((aq))^(-)hArrFe(OH)_(3(S)^(+))`

Text Solution

Verified by Experts

(i) `K_(C)=([NO]^(2)[Cl_(2)])/([NOCl]^(2))`
(ii) `K_(C)=[NO_(2)]^(4)[O_(2)]`
(iii) `K_(C)=([CH_(3)COOH][C_(2)H_(5)OH])/([CH_(3)COOC_(2)H_(5)])`
(iv) `1/([Fe^(3+)][OH^(-)]^(3)`
In the above expressions the concentrations of solids and water are taken as unity.
