Chapter 5, Problem 5.32E

For the reaction

$\text{AgCl}\left(\text{s}\right)\rightleftharpoons {\text{Ag}}^{\text{+}}\left(\text{aq}\right)+{\text{Cl}}^{-}\left(\text{aq}\right)$

$K=1.8\times {10}^{-10}$. (a) Using ${\text{Δ}}_{\text{f}}G\text{°}\left[\text{AgCl}\left(\text{s}\right)\right]$ in Appendix $2$, determine ${\text{Δ}}_{\text{f}}G\left[{\text{Ag}}^{\text{+}}\left(\text{aq}\right){\text{+Cl}}^{-}\left(\text{aq}\right)\right]$. (b) If ${\text{Δ}}_{\text{f}}G\left[{\text{Cl}}^{-}\left(\text{aq}\right)\right]=-131.\text{3 kJ}$, what is ${\text{Δ}}_{\text{f}}G\left[{\text{Ag}}^{\text{+}}\left(\text{aq}\right)\right]$?
