Consider the following \( \mathrm{E}^{\circ} \) values:
math xmlns=http://www.w3.org/1998/Math/MathMLmsubsupmi mathvariant=normalE/mimrowmsupmiFe/mimrowmn3/mnmo+/momo//mo/mrow/msupmo//momsupmiFe/mimrowmn2/mnmo+/mo/mrow/msup/mrowmn0/mn/msubsupmo=/momo+/momn0/mnmo./momn77/mnmo /momi mathvariant=normalV/mimo;/momsubsupmi mathvariant=normalE/mimrowmsupmiSn/mimrowmn2/mnmo+/mo/mrow/msupmo//momsupmiSn/mimn0/mn/msup/mrowmn0/mn/msubsupmo=/momo-/momn0/mnmo./momn14/mnmo /momi mathvariant=normalV/mi/math
Under standard conditions the potential for the reaction is
\( \mathrm{Sn}(\mathrm{s})+2 \mathrm{Fe}^{3+}(\mathrm{aq}) \rightarrow 2 \mathrm{Fe}^{2+}(\mathrm{aq})+\mathrm{Sn}^{2+}(\mathrm{aq}) \)
(A) \( 1.68 \mathrm{~V} \)
(B) \( 1.40 \mathrm{~V} \)
(C) \( 0.91 \mathrm{~V} \)
(D) \( 0.63 \mathrm{~V} \)
