For the half reaction
$B (s)$ $\to$ $B^{2 +} + 2 e^{-}$ $E_{1}^{\circ} = - 0.44 V$
and
$B^{2 +}$ $\to$ $B^{3 +} + e^{-}$ $E_{2}^{\circ} = 1.3 V$
What is $E_{3}^{\circ}$ for the reaction
$3 e^{-} + B^{+ 3}$ $\to$ B(s):
$0.86 V$
$0.14 V$
$- 0.14 V$
$- 0.28 V$

$B (s) \to B^{2 +} + {2 e}^{-} E_{1}^{0} = - 0.44 V$
+ $B^{2 +} \to B^{3 +} + e^{-} E_{2}^{0} = + 1.3 V - ----------------------------------- -$
$B (s) \to B^{3 +} + {3 e}^{-}; E_{3}^{0} = 1.3 - 0.44 V$
$= 0.86 V$
