135. Solving a chemistry problem

Calculate the Gibbsian adsorption and plot the adsorption isotherm according to the dependence b=f(c) of its aqueous solutions at T=293 K. Graphically determine the magnitude of the surface activity and calculate the adsorption at c=0.02 mol/l. Determine the maximum adsorption, calculate the parameters of the adsorption layer
