1. Data for the equilibrium adsorption of pure methane gas on activated carbon at 296 K were obtained by Ritter and Yang: q, cm³ of CH4/B 45.5 91.5 113 121 125 126 126 carbon P = p, psia 40 165 350 545 760 910 970 Fit the data to: a.) the Freundlich isotherm, and obtain its equation and b.) the Langmuir isotherm and obtain its equation. Set up a table of values of the experimental q, the Freundlich q and the Langmuir q. Which isotherm fits the data significantly better?
