124. Solving a chemistry problem
4. Using the BET equation, calculate the specific surface area of the adsorbent from the nitrogen adsorption data:
p/ps 0.1 0.2 0.3 0.4
A*103, m3/kg 0.71 0.31 0.93 1.09
The area occupied by a nitrogen molecule in a dense monolayer is 0.16 nm2, nitrogen density is 1.25 kg/m3
