MCQ

Which of the following relation represents correct relation between standard electrode potential and equilibrium constant ?

$I$. $\log \,\,K\, = \,\frac{{nF{E^o}}}{{2.303\,RT}}$

$II$. $K\, = \,{e^{\frac{{nF{E^o}}}{{RT}}}}$

$III$. $\log \,\,K\, = -\,\frac{{nF{E^o}}}{{2.303\,RT}}$

$IV$. $\log \,\,K\, = 0.4342\,\,\frac{{-nF{E^o}}}{{RT}}$

Choose the correct statement $(s)$.

A
$I,\, II$ and $III$ are correct
B
$II$ and $III$ are correct
✓
$I,\, II$ and $IV$ are correct
D
$I$ and $IV$ are correct

✓

Answer

Correct option: C.

$I,\, II$ and $IV$ are correct

c
$\Delta G\, = \, - \,2.303\,RT\,\log \,K$

$ - \,nF{E^o}\, = \, - \,2.303\,RT\,\log \,K$

$\log \,K\, = \,\frac{{nF{E^o}}}{{2.303\,RT}}$

$ = \,0.4342\,\frac{{nF{E^o}}}{{RT}}$ ..... $(i)$

$\ln \,K\, = \,\frac{{nF{E^o}}}{{RT}}$

$K\, = \,{e^{\frac{{nF{E^o}}}{{RT}}}}$ .... $(ii)$
