Consider a sample of aluminum oxide with a surface area of 100 m2/g. The BET model is used to measure the multilayer adsorption of nitrogen gas on the surface of the aluminum oxide. The experimental data obtained at 77 K is as follows:P/Po = 0.001 0.003 0.01 0.03 0.1 0.3 0.5 0.7 0.9 0.99 V(mL/g) = 7.15 23.20 69.15 194.10 587.58 876.59 962.23 1011.18 1049.03 1059.65Determine the BET constant, BET adsorption capacity, and the monolayer adsorption capacity for the aluminum oxide.
