3) Calculate the critical value of interfacial tension, determined by the Rehbinder criterion, below which spontaneous dispersion occurs. The temperature is 200 C, the size of the formed particles is 1*10-6 cm, the logarithm of the ratio of the number of particles of the dispersed phase to the number of molecules of the dispersion medium is y=15.
