For the system of N2 or Ar adsorbed on graphite samples, a few adsorption anomalies were found and briefly discussed in previous papers. This paper discusses the causes of the anomalous agreement between the calculated values of N2 and Ar monolayer volumes Vm. According to the facts that the molecular size of nitrogen is different from that of argon, and that physisorption of gases on solids is generally considered to take place with a closepacked first layer, it seems unusual that both Vm value coincide. This unexpected phenomenon can be explained in terms of the geometry of the adsorbate molecules and the adsorbent graphite, and the electrostatic attraction between the adsorbed molecule and the graphite.
