Concept introduction:
The equilibrium constant is a parameter which describes the relationship between concentration of the reactants and the products at equilibrium stage. Equilibrium constant of a reaction is expressed by the ratio of concentration of product species raised to the power of their stoichiometric coefficients to the concentration of reactant species raised to the power of their stoichiometric coefficients.

Answer to Problem 8.54E
The shift in the equilibrium will be towards the right direction and white solid will be formed due to the formation of lead chloride.
Explanation of Solution
According to the Le Chȃtelier’s principle the change in concentration, volume, pressure and temperature affects the equilibrium of the reaction.
The given equilibrium reaction is shown below.
It is considered that whenequilibrium mixture is cooled, the temperature on right hand side decreases. Hence, according to the Le Chȃtelier’s principle, the equilibrium will shift towards right direction to compensate the decrease in temperature. Thus, the white solid would be formed due to the formation of lead chloride.
The shift in the equilibrium will be towards the right direction and white solid will be formed due to the formation of lead chloride.
