117. Solving a chemistry problem

The data in the following table describes the adsorption of acetic acid from its solution on charcoal at 25 degrees: С, mol/dm3 0.05 0.10 0.50 1.00 1.50 m*, g 0.045 0.061 0.11 0.148 0.178 m* is the mass of acid adsorbed by 1 gram of coal. Determine which equation - Langmuir or Freundlich - describes this data better and find the coefficients of this equation.
