Chapter 18, Problem 29E

Interpretation Introduction

Interpretation:

The direction of the equilibrium for $\text{Cu}{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}{}^{2+}\left(\text{aq}\right)\rightleftarrows {\text{Cu}}^{2+}\left(\text{aq}\right)+4{\text{NH}}_{\text{3}}\left(\text{aq}\right)$ when concentration of ammonia is reduced is to be predicted. The explanation regarding this is to be stated.

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.
