Given: $\mathrm { E } _ { \mathrm { Fe } ^ { 3 + } / \mathrm { Fe } } ^ { \circ } = -0.036 \mathrm {~V} , \quad \mathrm { E } _ { \mathrm { Fe } ^ { 2 + } / \mathrm { Fe } } ^ { \circ } = -0.439 \mathrm {~V}$. The value of standard electrode potential for the change, $\mathrm { Fe } _ { ( \mathrm { aq } ) } ^ { 3 + } + \mathrm { e } ^ { - } \rightarrow \mathrm { Fe } ^ { 2 + } ( \mathrm { aq } )$ will be:\\
(1) $-0.072$ V\\
(2) $0.385$ V\\
(3) $0.770$ V\\
(4) $-0.270$ V
