                    Mechanism of adsorption of H₂ under atmospheric pressure by Co precipitated on infusorial earth is the same as in the case of pure Co, but A, determined by the number of active adsorbing centers, is much greater for the supported catalyst.  The values of K, measuring the velocity of adsorption, are small, perhaps because the activity of adsorbing centers increases and most of them are instantly saturated, so that only the adsorption of less active centers is within the scope of measurement.  Variation in A with temperature shows the same tendency as in the previous case.
