The correct option(s) about entropy (S) is(are)

A)  $\Delta S=nF\frac{dE}{dt}=6F\times \frac{2R}{3F}=4R$
B) The cell is spontaneous and there is decrease in concentration on moving from reactant side to product side and hence  $\Delta S>0$
$\begin{array}{l}A{g}^{+}\left(0.2M\right)\stackrel{ }{\to }A{g}^{+}\left(0.1M\right)\\ E=-\frac{0.06}{1}\log \frac{0.1}{0.2}>0\end{array}$
C) Racemization leads to increase in entropy as randomness increases.
D)  $\Delta S>0$ for micellization due to release of solvated water molecules from the hydrophilc head of surfactant molecules.
