Kern and Findenegg measured the adsorption of n- docosane (C22H46) in hexane on the surface of porous graphite with a specific surface area of 68 mg-1 which was analyzed by the method BET Assume that the adsorption is monolayer and Imax is 88.9 umol/g Find 2 15.1 What area is occupied by one molecule compared to the actual molecular size of n- docosane (C22H46) where the cross-section of the alkane chain is 4.58 x 4.5 and the average length of the C-C bond is 1.2 . 15.2 We can infer how the n-docosane molecules line up on the graphite surface
