5. Calculate and plot the characteristic curves for benzene and chloroform, as well as the adsorption isotherm of chloroform at 293 K based on the adsorption data of benzene on microporous activated carbon at 293 K:
p, Pa 0.13 0.51 1.30 3.33 16.7 37.3 95.6 319.8
A, mol/kg 1.13 1.69 2.25 2.82 3.94 4.50 5.25 5.77
The affinity coefficient for chloroform is 0.87 (the standard substance is benzene). The saturated vapor pressure of benzene and chloroform at this temperature is 10.47*103 Pa and 23.99*103 Pa, respectively, the density of liquid benzene is 0.879 g/cm3 and chloroform is 1.480 g/cm3.
