Why? Could your cell have a commercial value?
2.4 What are the cell reactions and their emfs in the following systems? Are the reactions spontaneous?
Assume that all systems are aqueous.
(a) Ag/AgCl/K$^{+}$, Cl$^{-}$ (1 M)/Hg$_{2}$Cl$_{2}$/Hg
(b) Pt/Fe$^{3+}$ (0.01 M), Fe$^{2+}$ (0.1 M), HCl (1 M)//Cu$^{2+}$ (0.1 M), HCl (1 M)/Cu
(c) Pt/H$_{2}$ (1 atm)/H$^{+}$, Cl$^{-}$ (0.1 M)//H$^{+}$, Cl$^{-}$ (0.1 M)/O$_{2}$ (0.2 atm)/Pt
(d) Pt/H$_{2}$ (1 atm)/Na$^{+}$, OH$^{-}$ (0.1 M)//Na$^{+}$, OH$^{-}$ (0.1 M)/O$_{2}$ (0.2 atm)/Pt
(e) Ag/AgCl/K$^{+}$, Cl$^{-}$ (1 M)//K$^{+}$, Cl$^{-}$ (0.1 M)/AgCl/Ag
(f) Pt/Ce$^{3+}$ (0.01 M), Ce$^{4+}$ (0.1 M), H$_{2}$SO$_{4}$ (1 M)//Fe$^{2+}$ (0.01 M), Fe$^{3+}$ (0.1 M), HCl (1 M)/Pt
