220. The following table shows data on the dependence of the volume of adsorbed carbon monoxide (reduced to normal conditions) on pressure.
Adsorption on a mica sample at 85 K.
p, mmHg 100 200 300 400 500 600
V, cm3 0.126 0.155 0.167 0.174 0.179 0.182

a) Determine which Langmuir or Freundlich equation best describes these data, b) What is the maximum volume of adsorbed gas? c) Determine the adsorption constant KL or KF. d) What volume is adsorbed at a CO pressure of 1 atm.
