125. Based on the results of measurements of the surface tension of solutions of n-octyl alcohol in water at 39.0 ° C, depending on the concentration (table below), find the limiting adsorption of alcohol G∞ using a graphical method, and calculate the area occupied by 1 molecule of alcohol in a saturated adsorption layer, assuming a monomolecular adsorption.
C, mmol/L 0 0.14 0.29 0.38 0.58 0.77 1.16 1.54 2.31
b, mN/m 70.1 68.9 65.9 62.8 61.0 55.8 51.1 45.9 40.5
