Use tabulated electrode potentials to calculate for each

Chapter 18, Problem 65E

(choose chapter or problem)

Use tabulated electrode potentials to calculate \(\Delta G_{\mathrm{rxn}}^{\circ}\) for each reaction at \(25\ ^{\circ}\mathrm{C}\).

a. \(\mathrm{Pb}^{2+}(a q)+\mathrm{Mg}(s) \longrightarrow \mathrm{Pb}(s)+\mathrm{Mg}^{2+}(a q)\)

b. \(\mathrm{Br}_2(l)+2\mathrm{\ Cl}^-(aq)\longrightarrow2\mathrm{\ Br}^-(aq)+\mathrm{Cl}_2(g)\)

c. \(\mathrm{MnO}_2(s)+4\mathrm{\ H}^+(aq)+\mathrm{Cu}(s)\longrightarrow\mathrm{Mn}^{2+}(aq)+2\mathrm{\ H}_2\mathrm{O}(l)+\mathrm{Cu}^{2+}(aq)\)
