2. Calculate the specific surface area of the catalyst if krypton adsorption at 77.5 K is characterized by the following data
P, mmHg 0.447 0.645 1.159 1.450
V, cm3/g 0.4185 0.4619 0.5234 0.6313
Catalyst weight 13.03g. The area occupied by one krypton molecule: 19.2*10-20 m2. The krypton area at 0C is 3.739 g/l. Saturated krypton vapor pressure 342.65 Pa
