       Adsorption was measured at 0° for H₂ on a supported Ni catalyst poisoned with CO.  A small quantity of poison causes an increase of H₂ adsorption at all pressures up to 1 atm.  A large amount of poison gives a slight low-pressure increase and a high-pressure decrease of adsorption.  Larger amounts of poison decrease the rate of adsorption.
