In an experiment to measure the adsorption of CO2 on activated carbon by physi-sorption at 273K, the data reported in the above table were collected by the students. i. Plot the graph of P versus P/V and confirm if it fits Langumir isotherm or not? ii. Find the constant K and the volume corresponding to complete monolayer adsorption (Vmon). iii) Calculate the fraction of charcoal surface which is covered by CH4 molecules at P=80 kPa.
