Vedclass · Answer

(C) Micelle formation is a spontaneous process driven by the hydrophobic effect.During micelle formation,the hydrophobic tails of surfactant molecules aggregate,which leads to the release of water molecules previously ordered around the tails into the bulk solvent.This release of water molecules results in a net increase in the entropy of the system,so $\Delta S > 0$.Additionally,the process is endothermic,meaning $\Delta H > 0$.Therefore,statements $B$ and $C$ are correct.

For micelle formation,which of the following statements are correct?
$A$. Micelle formation is an exothermic process.
$B$. Micelle formation is an endothermic process.
$C$. The entropy change is positive.
$D$. The entropy change is negative.
