111. Determine the Langmuir adsorption isotherm constants for solutions of hexyl and heptyl alcohols. Does Traube's rule hold in this case? The dependence of the adsorption of these compounds on the concentration is given in the table:

Hexyl alcohol Heptyl alcohol
С, mmol/l G, µmol/m3 С, mmol/l G, µmol/m2
9.35 0.875 3.84 1.11
18.75 1.735 5.0 1.45
31.0 2.51 6.55 1.82
55.5 3.78 12.5 2.78
110.5 5.65 26.0 4.92
