Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

Multi-component adsorption isotherm is determined experimentally when He, H2 (or D2) and CH4 are adsorbed on activated carbon (AC) plated on a cryopanel cooled at cryogenic temperature and desorbed at room one. It is correlated to the Langmuir-Freundlich-type one. The equilibrium isotherms for their respective single-component adsorption processes are correlated in terms of the Langmuir-Freundlich-type ones, and the isotherm when the three components of He, H2 and CH4 are adsorbed at the same time is correlated in terms of a naturally-extended multi-component one without any changes in the original constants included in the single-component one. Rates of the isotopic exchange reaction of D atom between CH4 and D2 on AC between 10 K and room temperature are also determined. After eliminating the effects of natural isotope of 13C included in CH3D, CH2D2, CHD3, CD4 on mass-spectrometric measurements, it was found that the isotopic exchange rate of CH4 + D2 = CH3D +HD and so on was found to be so late that any detectable effect was not observed.
