phenol $\xrightarrow[{reaction}]{{\operatorname{Re} imer - Tiemann}}X\xrightarrow[{(ii)\,{H^ \oplus }}]{{(i)\,NaOH\,conc}}Z$
Product $Z$ is

$Pt ( s )\left| H _2( s )( latm )\right| H ^{+}\left( aq ,\left[ H ^{+}\right]=1\right)|| Fe ^{3+}( aq ), Fe ^{2+}( aq ) \mid \operatorname{Pt}( s )$
Given : $E _{ Fe ^{3+} / e ^{2 *}}^0=0.771\,V$ and $E _{ H ^{+}+\frac{1}{2} H _2}^0=0 V , T =298\,K$
If the potential of the cell is $0.712\,V$ the ratio of concentration of $Fe ^{2+}$ to $Fe ^{2+}$ is $........$.(Nearest integer)
