1. Adsorption Equilibrium. Experimental equilibrium data for the adsorption of methane on Calgon Carbon Corp. PCB activated carbon are listed in table below. Determine if the Langmuir isotherm is a good fit to the data at T = 373 K. (Hint: From the given p/q and p, solve for QA max and Kap. Plot your own isotherm (q vs. p) (you can use the p values, but you need an expression for q as a function of p) and see if that agrees with the given values.
