Write the equilibrium constant expressions for K_c and for K_p, if applicable, for the following reactions.

(a) ${\text{2NO}}_2(g)+7{\text{H}}_{\text{2}}(g)\rightleftarrows 2{\text{NH}}_3(g)+4{\text{H}}_{\text{2}}\text{O}(l)$

(b) $\text{2Zns}(s)+3{\text{O}}_{\text{2}}(g)\rightleftarrows \text{2ZnO}(g)+2{\text{SO}}_2(l)$

(c) $\text{C}(s)+{\text{CO}}_{\text{2}}(g)\rightleftarrows \text{2CO}(g)$

(d) ${\text{C}}_{\text{6}}{\text{H}}_{\text{5}}\text{COOH}(aq)\rightleftarrows {\text{C}}_{\text{6}}{\text{H}}_{\text{5}}{\text{COO}}^{-}(aq)+{\text{H}}^{\text{+}}(aq)$
