Question Three The following data were reported for the adsorption of N2 on 8 mg mica (a group of silicate minerals) at 0 °C. The volume of N below is the volume that the gas would occupy at STP (O°C and 1 atm). Pressure/Pa 0.293 0.506 0.973 1.773 3.479 Volume/mm3 12.0 17.0 23.9 28.2 33.0 (a) Show that the data fit the Langmuir isotherm and evaluate the constants constant K and V, in the expression. (4) (b) Given that the cross-sectional area of a nitrogen molecule is 0.150 nm?, calculate the specific surface area of the mica (in m/g). (5)
