When plotted according to the linear form of the BET equation, data for the adsorption of N2 on Graphon at 77 K give an intercept of 0.005 and a slope of 1.5 (both in cm3 STP per gram). Calculate Asp assuming a molecular area of 16 (angstrom)2 for N2. Calculate also the heat of adsorption for the first layer (the heat of condensation for N2 is 1.3 kcal/mol). Would your answer for Vm be much different if the intercept were taken to be zero (and the slope the same)? Comment briefly on the practical significance of your calculation.
