Question
1. Calculate the theoretical potential of the following cells.
Indicate whether the reaction will proceed spontaneously
in the direction considered (oxidation on the left, reduction
on the right) or whether an external voltage source is
needed to force this reaction to occur.
(a)Pb | Pb2*(0.120 M) || Cd2*(0.0500) |Cd
(b) Zn |Zn2*(0.0420M)|| TI3*(9.06x10-?M), TI*(0.0400M) |Pt
(c) Pb | Pbl2(sat'd), 1(0.0220 M) || Hg²+(2.60x10 M) |Hg
