Problem

For the equilibrium reaction 2AgCl(s)⇌2Ag+(aq)+2Cl−(aq)2\text{AgCl}(s) \rightleftharpoons 2\text{Ag}^+(aq) + 2\text{Cl}^-(aq) which of the following species must be omitted when the equilibrium-constant expression KcK_c is written for the reaction? (a) AgCl(s) and Ag+(aq)\text{AgCl}(s)\text{ and }\text{Ag}^+(aq) (b) Ag+(aq) and Cl−(aq)\text{Ag}^+(aq)\text{ and }\text{Cl}^-(aq) (c) AgCl(s)\text{AgCl}(s) only (d) None of the species are omitted
