(Critical micelle concentration ($CMC$) is marked with an arrow in the figures.)
$E_{F{e^{ + 2}}/Fe}^o =- 0.44\,V$ and $E_{Au/A{u^{ + 3}}}^o = - 1.50\,V$
$I$. $\log \,\,K\, = \,\frac{{nF{E^o}}}{{2.303\,RT}}$
$II$. $K\, = \,{e^{\frac{{nF{E^o}}}{{RT}}}}$
$III$. $\log \,\,K\, = -\,\frac{{nF{E^o}}}{{2.303\,RT}}$
$IV$. $\log \,\,K\, = 0.4342\,\,\frac{{-nF{E^o}}}{{RT}}$
