2. Based on the experimental data of capillary condensation of methanol on silica gel at 293 K, construct a hysteresis loop. Using the desorption branch, construct the integral and differential pore size distribution curves.
p/ps 0.2 0.4 0.6 0.8 0.9 1.0
Value A, mol/kg 0.8 1.3 1.6 2.2 4.0 3.9
desorption 0.8 1.3 1.7 3.0 3.7 3.9
At the indicated temperature, the molar volume of methanol is 40.6 cm3/mol, surface tension b=22.6*10-3 J/m2.
