\( \mathrm{E}^{\circ} \) for the half cell reactions are as,
(A) \( \mathrm{Zn}=\mathrm{Zn}^{2+}+2 \mathrm{e}^{-} \) \( \mathrm{E}^{\circ}=+0.76 \mathrm{~V} \)
(B) \( \mathrm{Fe}=\mathrm{Fe}^{2+}+2 \mathrm{e}^{-} \) \( \mathrm{E}^{\circ}=+0.41 \mathrm{~V} \)
The \( \mathrm{E}^{\circ} \) for given cell reaction, \( \mathrm{Fe}^{2+}+\mathrm{Zn} \rightarrow \mathrm{Zn}^{2+}+\mathrm{Fe} \) is:
(A) \( -0.35 \mathrm{~V} \)
(B) \( +0.35 \mathrm{~V} \)
(C) \( +1.17 \mathrm{~V} \)
(D) \( -0.17 \mathrm{~V} \)
