5. When adsorption of propionic acid from a solution in benzene on colloidal nickel, the following data were obtained:
A*105, mol/kg 2.0 3.6 4.0 4.3 4.4
C, mmol/l 0.2 2.0 3.6 5.0 10
Calculate the constants of the Langmuir equation, determine the specific surface area of the adsorbent. The density of propionic acid is 0.992 g/cm3.
