Q. An oxidation-reduction reaction in which $3$ electrons are transferred has a $ΔG^\circ $ of $-17.37kJmol^{- 1}$ at $25^\circ C$ . The value of $E^\circ _{cell }$ (in $V$ ) is $y\times 10^{- 2}$ . The value of $y$ is
Give your answer as the nearest integer.
$\left(1 \quad F =96,500 \quad C \quad mol ^{-1}\right)$

Solution:

$ΔG^\circ =-nFE^\circ $
$-17.37\times 1000=-3\times 96500\times E^\circ $
$E^\circ =\frac{17370}{3 \times 96500}$
$E^\circ =\frac{579}{9650}volt$
$=0.06=6\times 10^{- 2}volt$
