84. Solving a chemistry problem
3. The specific surface area of nonporous carbon black is 94. Calculate the area occupied by a toluene molecule in a dense monolayer based on the data on the adsorption of benzene on this adsorbent at 283 K:
P*10-2 Pa 5.33 9.87 17.33 23.06 45.53
a*103, mol/kg 14.9 19.1 24.2 27.3 36.8
(p is the equilibrium vapor pressure, a is the adsorption value). The isotherm is described by the Langmuir equation.
