Chapter 14, Problem 14.58SP

For each of the following equilibria, write the equilibrium constant expression for K_c. Where appropriate, also write the equlibrium constant expression for K_p.

(a) ${\text{Fe}}_{\text{2}}{\text{O}}_{\text{3}}\left(\text{s}\right)\text{+3CO}\left(\text{g}\right)\rightleftarrows {\text{2Fe(l)+3CO}}_{\text{3}}\left(\text{g}\right)$

(b) $\text{4Fe}\left(\text{s}\right){\text{+3O}}_{\text{2}}\left(\text{g}\right)\rightleftarrows {\text{2FeO}}_{\text{3}}\left(\text{s}\right)$

(c) ${\text{BaSO}}_{\text{4}}\left(\text{s}\right)\rightleftarrows \text{BaO}\left(\text{s}\right){\text{+SO}}_{\text{3}}\left(\text{g}\right)$

(d) ${\text{BaSO}}_{\text{4}}\rightleftarrows {\text{Ba}}^{\text{+2}}\left(\text{aq}\right){\text{+SO}}_{\text{4}}{}^{\text{2-}}\left(\text{aq}\right)$
