고체 표면 위에서 기체의 물리 흡착(Ⅱ)

Adsorption of Gases on Solid Surfaces(Ⅱ)

  The theoretical approach to thermodynamic properties of the adsorbed layer is founded by the statistical thermodynamics. It is assumed that the adsorbed layer possesses the degrees of freedom both of the gas-like and the solid-like. The gas-like phase is described as an ideal gas and the solid-like phase as an Einstein oscillator. Molecular aspects of the parameters are averaged out to molar quantities i.e. E₁ and E<SUB>n</SUB>.   Discontinuity of entropies of the adsorption reveal the evidences of the first order phase transition in the adsorbed layer. Heat capacities from the partition function formulated here are also the another pieces of the l-st order one.   It is convinced that adsorption phenomena could be explained as 2-dimensional liquid in this work.
