Using the Reduction Half-Reactions,write an Overall Reaction in the Direction

question 37

Multiple Choice

Using the reduction half-reactions,write an overall reaction in the direction that is spontaneous.Calculate E°.
$\begin{array}{ll}\mathrm{AgI}(s) +e^{-} \rightarrow \mathrm{Ag}(s) +\mathrm{I}-(a q) & E_{\mathrm{red}}^{0}=-0.152 \mathrm{~V} \\\mathrm{Co}^{3+}(a q) +e^{-} \rightarrow \mathrm{Co}^{2+}(a q) & E_{\mathrm{red}}^{\circ}=+1.953 \mathrm{~V}\end{array}$

• A) Co²⁺(aq)+ AgI(s)? Co³⁺(aq)+ Ag(s)+ I?(aq)E° = ?2.105 V
• B) Co²⁺(aq)+ Ag(s)+ I?(aq)? Co³⁺(aq)+ AgI(s)E° = ?1.801 V
• C) Co³⁺(aq)+ Ag(s)+ I?(aq)? Co²⁺(aq)+ AgI(s)E° = +1.801 V
• D) Co³⁺(aq)+ Ag(s)+ I?(aq)? Co²⁺(aq)+ AgI(s)E° = +2.105 V
• E) Co³⁺(aq)+ AgI(s)? Co²⁺(aq)+ Ag(s)+ I?(aq)E° = ?2.105 V
