| Abstract: | Correlation between the temperature at which a base is desorbed and the acid strength (Ho) of the sites set free by it, was looked for. Ammonia was employed as base. A linear correlation of the type Ho= + /T (K) is valid with and constants, dependent on the adsorbate and the adsorbent.
