The DS
m values are small at low temperatures and increase by
increasing the temperature. The calculated DS
m values are always
large positive as shown in figure 9 for all the systems indicating
that the micellization is entropy driven process. Calculated
DG
m; DH
m and DS
m values are illustrated in table 3.
A Linear relation between DH
m and DS
m of micellization was
observed [33,34]. This phenomenon is called enthalpy–entropy
compensation. The enthalpy–entropy compensation plot is shown
in figure 10.
