Abstract

IN a recent note under this title, Ward and Tordai1 have pointed out that the interfacial tension between water and hexane solutions of lauric acid attains equilibrium at an anomalously slow rate, and suggest that this arises from a process of high activation energy being involved subsequent to the diffusion of solute molecules to the interface. The observed marked effect of temperature in hastening equilibrium was taken as support for this view.
