3 When studying the adsorption of acetic acid on animal charcoal at 25°C, the following results were obtained:
V (CH3COOH solution) \u003d 0.100 l, m (coal) \u003d 10 g

C0, mol/l 0.485 0.655 0.883 1.236 2.511
Cequiv, mol/L 0.018 0.031 0.062 0.126 0.471

a) Calculate the values of specific adsorption in each of the five solutions,
b) determine the constants K and n of the Freindlich equation by a graphical method,
c) calculate specific adsorption at Ср = 0.1 mol/l
