126. Solving a chemistry problem

Calculate the specific adsorption using the Gibbs equation and plot the adsorption isotherm of substance A from the dependence of the surface tension of its aqueous solutions on the concentration at temperature T (Table 4). Determine the value of the limiting adsorption A∞ and the constant K in the Langmuir equation.
