Explanation:
Hello.
In this case, since we apply the law of mass action in order to write the equilibrium expression for each chemical reaction, we proceed as follows:
a. The reaction is:
And the equilibrium expression:
Since all the species are in gaseous phase they are included on the equilibrium expression.
b. The reaction is:
And the equilibrium expression:
Since only copper (II) ions and silver (I) ions are in aqueous phase.
c. The reaction is redox and it turns out:
And the equilibrium expression:
Since all the species are in aqueous phase.
