        Difficulties in measurement of the velocity of decomposition of alcohols on ZnO surface are discussed.  The importance of the adsorption of H₂O in the decomposition of alcohols is shown.  Evidence for an activated adsorption of H₂O on ZnO is given.  The velocity of adsorption of H₂ by ZnO was measured in the range 0°-360°; isotherms were obtained at -191° and -78.5°.  The heats of adsorption of 2 types of adsorption of H₂ by ZnO were determined.  A theory of activated adsorption is developed mathematically, which gives expressions for the temperature of maximum adsorption.  Methods of calculating the activation energy and heat of adsorption are given.
