Chapter 19, Problem 20E

Write the half-cell reactions and the balanced chemical equation for the electrochemical cells diagrammed here. Use date from Table 19.1 and Appendix D to calculate $E_{\text{col}}^{°}$ for each reaction.

a. $\text{Cu}\left(\text{s}\right){\text{|Cu}}^{\text{2+}}{\text{||Cl}}^{\text{-}}\left(\text{aq}\right)|\text{Cu}\left(\text{s}\right)$

b. $\text{Ag}\left(\text{s}\right)\text{|Agl}\left(\text{s}\right)\left|{\text{l}}^{\text{-}}\left(\text{aq}\right)\right|\text{AgCl}\left(\text{s}\right)|\text{Ag}\left(\text{s}\right)$

c. ${\text{Pt|Ce}}^{\text{44}}\left(\text{aq}\right),{\text{Ce}}^{\text{2+}}\left(\text{aq}\right)\left|\right|{\text{l}}^{\text{-}}\left(\text{aq}\right)\left|\text{l}{\text{2}}_{}\left(\text{s}\right)\right|\left(\text{s}\right)$

d. $\text{U}\left(\text{s}\right){\text{|U}}^{\text{2+}}\left(\text{aq}\right)\left|\right|{\text{V}}^{\text{2+}}\left(\text{aq}\right)\text{|V}\left(\text{s}\right)$
