24. In measuring the surface tension of aqueous solutions of propionic acid at T = 293 K, the following values were obtained:
Concentration C, mol / dm3 0 0.1 0.24 0.95 2.0
Surface tension σ⋅103, N / m 73.3 65.5 60.0 45.7 38.8
Based on these data, construct the graphs σ = f (C) and Γ = f (C). Determine the constants of the Langmuir equation K and Г∞.
