An oxidation-reduction reaction in which 3 electrons are transferred has a ${\Delta G}^{0} of 17 . 37kJ{mol}^{- 1} at$ 25 ° C . $The value of$ {E}_{cell}^{o} $(in V) is$ _ _ _ _ _ _ _ \times {10}^{- 2} $.</p><p>\left(1F = 96500C{mol}^{- 1}\right)$

Correct answer

Step-by-step solution

$\Delta G ° = - nF{E}_{cell}^{o}$

$17 .37 \times {10}^{3} = - 3 \times 96500 \times {E}_{cell}^{o}$

${E}_{cell} = - 0 .06 V$
