Question

16. The following data refer to the adsorption of nitrogen on 0.92 g of a sample of silica gel at 77 K, p being the pressure and V the volume adsorbed: 3.7 8.5 15.2 23.6 31.5 38.2 46.1 54.8 p/kPa Vicm3 (s.t.p.) 82 106 124 142 157 173 196 227 Saturated vapour pressure (Po)-101.3 kPa. Plot the adsorption isotherm and use the BET equation to calculate a specific surface area for the silica gel sample, taking the molecular area of nitrogen as 16.2 × 10-20 m2
