Explanation of Solution
Given reaction in the problem statement is,
Oxidation state of chlorine in chlorine molecule is zero. This gains an electron and gets converted into chloride ion. In the product side, the oxidation state of chlorine in
(b)
Interpretation:
Equilibrium constant expression for the given reaction has to be written.

Explanation of Solution
Given reaction in the problem statement is,
On seeing the above equation, it is found that there are different phases. Hence, this is an heterogeneous equilibria reaction. Therefore, for heterogeneous equilibria, the concentration symbol is used for the aqueous species and pressure symbol is used for gas-phase species. Liquids are not considered in this expression. Therefore, the equilibrium constant expression can be given as,
(c)
Interpretation:
Concentration of
