A disproportionation reaction is one in which an intermediate oxidation state "disproportionates" into a higher and lower oxidation state. Consider the following disproportionation reaction: ${\mathrm{Sn}}_{(29)}^{4+}+{\mathrm{Sn}}_{(0)}?2{\mathrm{Sn}}^{2+}(\text{ (a) })$ a. Use ${\mathrm{E}}^{?}$ values to calculate $?{\mathrm{G}}^{?}$ (at $25^{?}\mathrm{C}$ ) for this reaction. b. Use ${\mathrm{E}}^{?}$ values to calculate ${\mathrm{K}}_{\mathrm{eq}}$ (at $25^{?}\mathrm{C}$ ) for this reaction. Using the provided standard reduction potentials, calculate the standard free energy change and the equilibrium constant for the following reaction carried out at $298\mathrm{K}$. $4{\mathrm{Ag}}_{(0)}+{\mathrm{O}}_{2(?)}+4{\mathrm{H}}_{(?)}^{1+}?4{\mathrm{Ag}}_{(?+}^{1+}+{\mathrm{H}}_2{\mathrm{O}}_{?}$ Consider the following: $\begin{array}{l}=0.96\mathrm{V}\\ {\mathrm{Ag}}_{(\text{aqs }}^{+}+\mathrm{e}?{\mathrm{Ag}}_{(0)}\\ {\mathrm{Cr}}_2{\mathrm{O}}_7^{2+}+14{\mathrm{H}}^{+}+6{\mathrm{e}}^2?2{\mathrm{Cr}}^{3+}7{\mathrm{H}}_2{\mathrm{O}}_0{\mathrm{E}}_{\text{acd }}^{\mathrm{o}}=0.80{\mathrm{E}}^0=\\ 1.33\mathrm{V}\end{array}$ Rank the following in order of increasing oxidizing agent strength: ${\mathrm{NO}}_3^{+},{\mathrm{Ag}}^{+},{\mathrm{Cr}}_2{\mathrm{O}}_7^{2?}$ Consider the following: $\begin{array}{l}{\mathrm{I}}_{2(\mathrm{s})}+2{\mathrm{e}}^{?}?2{\mathrm{I}}_{(\mathrm{ies})}\\ {\mathrm{E}}^{?}=0.54\mathrm{V}\\ {\mathrm{Fe}}^{2+}+2\mathrm{e}?{\mathrm{Fe}}_{(0)}\\ {\mathrm{E}}_{\mathrm{ind}}^{\mathrm{T}}=\\ ?0.44\mathrm{V}\\ {\mathrm{Al}}^{3+}+3\mathrm{e}?{\mathrm{Al}}_{(0)}\\ {\mathrm{E}}_{\text{red }}^{?}=?1.66\mathrm{V}\end{array}$ Rank the following in order of decreasing reducing agent strength: $1,{\mathrm{Fe}}_{(\mathrm{s})},{\mathrm{Al}}_{(\mathrm{c})}$ Discuss the different types of isomerism. Be sure to include examples. Analysis of a metal complex shows ${\mathrm{Co}}^{3?}$ is bound to an unknown ligand in an octahedral arrangement. The complex is green in color and exhibits paramagnetic properties. Further analysis shows that the possible ligand bound to the ${\mathrm{Co}}^{34}$ could be $\mathrm{Cl}$ or $\mathrm{CN}$. Which ligand is most likely bound in the complex and explain your reasoning.
