Referring to Problem 8.9, calculate the value of Delta G for the process: AgCl (s) <--> Ag+(aq) + Cl-(aq) to yield a saturated solution at 298 K. (hint: use the well known equation Delta G = -RT ln K) (Note - Problem 8.9 is: The thermodynamic solubility product of AgCl(s) is 1.6 x 10^-10. What is [Ag+] in (a) 0.020 M KNO3 solution and (b) a 0.020 M KCl solution?)
