यदि \( E_{\mathrm{Fe}^{2} / \mathrm{Fe}}^{\circ}=0.441 \) वोल्ट और \( E_{\mathrm{Fe}^{3+} / \mathrm{Fe}^{2+}}^{\circ}=0.771 \) वोल्ट तो अभिक्रिया \( \mathrm{Fe}+2 \mathrm{Fe}^{+3} \rightarrow 3 \mathrm{Fe}^{+2} \) के लिए मानक विद्युत वाहक बल \( (\mathrm{emf}) \) होगा
(A) \( 0.330 \) वोल्ट
(B) \( 1.653 \) वोल्ट
(C) \( 1.212 \) वोल्ट
(D) \( 0.111 \) वोल्ट
