2 100 mL of a solution with a trichloroethylene (TCE) concentration of 200mg/L is placed in four small bottles containing variable doses of activated carbon. The samples are then placed

on a shaker table and allowed to equilibrate for one week. After this time period, the samples are filtered and the aqueous concentration of TCE is measured. The following data is obtained Determine the Freundlich isotherm parameters, KF and n, and plot the isotherm.
