Chapter 19, Problem 19.128QP

a Calculate ΔG° for the following cell reaction:

$\text{Tl}(s)|{\text{Tl}}^{+}(aq)||{\text{Pb}}^{2+}(aq)|\text{Pb}(s)$

The $\Delta G_f^{°}$ for Tl⁺(aq) is −32.4 kJ/mol.

b From ΔG°, calculate the standard cell potential for the cell reaction and from this, determine the standard potential for ${\text{Tl}}^{2+}(aq)+{\text{e}}^{-}\stackrel{}{\to }\text{Tl}(s)$.
