B The OL gives all the possible combinations of bound solute concentration and unbound solute concentration for the batch based on a mass balance. C The OL describes the progress of the adsorption process during batch adsorption. D The OL describes all the possible combinations of bound solute conc and unbound solute conc at equilibrium. A1. Answer B or C. Belter fig 6.2-1 shows the OL relative to the isotherm on a graph. The intersection of the two lines gives the final concs of bound and unbound solute for the batch.
