Ruthven and Kaul [Ind. Eng. Chem. Res., 32, 2047-2052 (1993)l measured adsorption isotherms for a series of gaseous aromatic hydrocarbons on well-defined crystals of NaX zeolite over ranges of temperature and pressure. For 1, 2, 3, 5-tetramethylbenzene at 547 K, the following equilibrium data were obtained with a vacuum microbalance:Obtain a best fit of the data to the linear, Freundlich, and Langmuir isotherms, with q in mol/g and pressure in atm. Which isotherm gives the bestfit?
