Calculating an Equilibrium Constant using Standard Free Energy Change Given that the standard free energies of formation of Ag'(aq), CI (aq), and AgCl(s) are 77.1 kJ/mol, -131.2 kJ/mol, and -109.8 kJ/mol, respectively, calculate the solubility product, Ksp, for AgCl. Solution The reaction of interest is the following: Ag (aq) +CI (aq) Ksp [Ag ICI] AgCl(s) The standard free energy change for this reaction is first computed...
