55. Solving a chemistry problem

2.8. When studying the adsorption of acetic acid on charcoal from aqueous solutions with a volume of 200 ml, the following results were obtained:
Mass of coal, g 3.96 3.94 4.00 4.12 4.04 4.00
Acid concentration before introduction of coal, mmol/l 503.0 252.2 126.0 62.8 31.4 15.7
equilibrium concentration of acid in solution, mmol/l 434.0 202.0 89.9 34.7 11.3 3.33
Show that these data satisfy the Freundlich adsorption isotherm. Calculate the constants of this equation.
