The BET equation for the adsorption of nitrogen on silica at 77 K can be expressed by the following equation (fitted in the range of reduced pressures between 0.05 and 0.3): p/V(Po _ P)= 2.8510^-4 + 0.0257 p /p0where the units of the slope and of the intercept are g/cm3. a. Estimate the volume for monolayer coverage V_m in cm3/g) and the parameter C of the BET equation. b. Estimate the specific surface area of solid silica (in m2/g) if the area occupied by one nitrogen molecule is 16.2 10 ^-20 m2

Exercise 3: The BET equation for the adsorption of nitrogen on silica at 77K can be expressed by the following equation (fitted in the range of reduced pressures between 0.05 and 0.3) : V(P0P)P=2.85104+0.0257P0P where the units of the slope and of the intercept are g/cm3. a. Estimate the volume for monolayer coverage Vm( in cm3/g) and the parameter C of the BET equation. b. Estimate the specific surface area of solid silica (in m2/g ) if the area occupied by one nitrogen molecule is 16.21020m2
