Chapter 19, Problem 28E

Consider the voltaic cell below.
$\text{Pt}\left(\text{s}\right)\left|{\text{Cr}}^{\text{2+}}\left(\text{aq}\right)\right|{\text{|V}}^{\text{2+}}\left(\text{aq}\right),{\text{V}}^{\text{2+}}\left(\text{aq}\right)|\text{C}\left(\text{s}\right)$
Use data from Appendix D to determine (a) the equation far the cell reaction. (b) $E_{{}^{col}}^{°}$ (c) ${\Delta }_{t}G°$ . (d) K; (e) whether the reaction goes essentially to completion at to a limited extent only, when the reactants and products in initially in their standard states.
