Question:

For the following reversible reactions, write thermodynamic equilibrium constant expressions, making appropriate substitutions for activities. Then relate K to Kc or Kp where this can be done.

(a) The water gas reaction

CO(g) + H(g) C(s) + HO(g) = CO(g)

(b) Formation of a saturated aqueous solution of lead(II) iodide, a very slightly soluble solute

Pbl(s)  Pb+(aq) + 25 (aq)

(c) Oxidation of sulfide ion by oxygen gas (used in removing sulfides from wastewater, as in pulp and paper mills).

O(g) + 2S(aq) + 2HO(1) + 2 HO(1)  4 OH(aq) + 2 S(s)
