I'm a little confused about the question because I don't remember exactly what this question asks off the top of my head, but I know that the two equations you've written here will both end up with charges balanced and a net 3+ on both sides of the one equation? If that helps
For this problem, we know deltaG for Tl3+/Tl. However, for b we want to know the deltaG for Tl3+/Tl+ in order to find whether or not Tl is disproportionate. We use the reaction potential for Tl+/Tl to calculate deltaG for the half-reaction and then combine the deltaG's for Tl3+/Tl and Tl+/Tl in a Hess's-law-like way to find the deltaG for Tl3+-->3e-+Tl+. Since deltaG is large and positive, the reverse reaction is greatly favored so Tl+ will be disproportionate.
