        Gauger and Taylor found that the amount of H₂ adsorbed by Ni decreases with rising temperature.  This is explained by assuming that H₂ molecules as well as H atoms are bound by the Ni atoms and that for every temperature a dynamical equilibrium between both forms is established.  A typical T-x curve for this equilibrium can be drawn from Gauger and Taylor’s data, showing that at the higher temperatures the adsorbed quantity of H₂ approaches asymptotically half the amount of H₂ adsorbed at the lowest temperature.
