Enthalpies of dilution of aqueous tetradecyltrimethylammonium bromide have been measured from 0.3 to about 0.002 mol-kg/sup -1/ and from 323 to 448 K at 1.03 MPa. Different methods of obtaining the enthalpy of micellization from experimental data are examined. Enthalpies of micellization calculated from these methods disagree by large amounts. From consideration of the temperature dependence of the average aggregation number and multiple equilibria equations for micellization, it is shown that there is an enormous dependence of micellization enthalpy on aggregation number of a micelle.
