Chapter 6, Problem 6D.6P

Interpretation Introduction

Interpretation: The standard Gibbs energy, enthalpy of formation and the standard entropy for ${\text{Cl}}^{\text{-}}\left(\text{aq}\right)$ in the $\text{AgCl}/{\text{Ag,Cl}}^{\text{-}}$ couple at $\text{298}\text{K}$ has to be calculated.

Concept introduction: The standard Gibbs energy determines the spontaneity of the reactions.  Positive values of standard Gibbs energy means the reaction is non-spontaneous while negative values mean the reaction is spontaneous.  Enthalpy of a reaction determines whether the reaction releases heat or requires heat.
