Given : $Cr _2 O _7^{2-} \rightarrow Cr ^{3+} ; E ^0=1.330\,V$ and
$\frac{2.303 RT }{ F }=0.059\,V$
The potential for the half cell reaction is $x \times 10^{-3}\,V$. The value of $x$ is $........$
$CH_3COOC_2H_5 + C_6H_5 -CH_2 -COOC_2H_5$ $\mathop {\xrightarrow{{{C_2}{H_5}ONa}}}\limits_{{C_2}{H_5}OH} $
$\begin{array}{*{20}{c}}
