One application of adsorption on surfaces is to measure the ability of acti- vated charcoal to adsorb acid. (Activated charcoal, a form of treated carbon, is very porous and is used to adsorb impurities from water. Its use in aquar- iums typifies this behavior.) In a lab experiment, a student mixes a given amount of powdered charcoal into a series of acetic acid solutions. The acetic acid solutions have different initial concentrations. Some of the acid is ad- sorbed onto the charcoal. By taking aliquots after equilibrium is established, the student determines the change in acid concentration. Plot a Langmuir isotherm for the experimental data and determine the equilibrium constant for the adsorption. The experimental data are as follows: Original concentration (M) 0.7001 Change in concentration (M) 0.3694 0.1515 0.0437 0.0169 0.00665 0.00588 0.00553 0.00283. 0.00153
