        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 Taylorís data, showing that at the higher temperatures the adsorbed quantity of H2 approaches asymptotically half the amount of H2 adsorbed at the lowest temperature.
