0Given :
\[
\begin{array}{l}
\mathrm{Mn}^{2+} \rightarrow \mathrm{MnO}_{4}^{-} ; \mathrm{E}^{0}=-1.51 \mathrm{~V} \\
\mathrm{MnO}_{2} \rightarrow \mathrm{Mn}^{2+} ; \mathrm{E}^{\circ}=1.23 \mathrm{~V}
\end{array}
\]
What is the \( E^{\circ} \) value for the reaction?
\[
\mathrm{MnO}_{4}^{-} \rightarrow \mathrm{MnO}_{2}
\]
(a) \( 1.7 \mathrm{~V} \)
(b) \( 2.74 \mathrm{~V} \)
(c) \( 5.09 \mathrm{~V} \)
(d) \( 1.1 \mathrm{~V} \)
