Abstract:

The above problem is treated by statistical mechanics under the corsideration that the amount of absorption of gas depends on the geometrical arrangement of gas particles in metal, if there is interaction among gas particles. The configuration of the arrangement of gas particles is introduced to the problem by the method of super-lattice formation in binary alloy. The result of calculation shows:
1. The effect of geometrical arrangement of gas particles to the amount of absorption appears when the interaction energy between gas particles is positive.
2. When the pressure of outer gas is constant, the influence of geometrical arrangement decreases the absorption amount as the temperature rises.
3. When temperature is constant, the influence of arrangement increases the absorption amount when the absorped amount is small, and decreases as the amount becomes large.
4 The experiment of the activated absorption of O2 by Ag suggests the existence of such effect of the geometrical arrangement of gas patticles in metals.
