The density profiles of the particles of a chemically reacting hard sphere fluid near a hard wall are studied. The theory pioneered by Cummings and Stell is utilized to provide the description of a bulk fluid. Different models of the particle-wall interactions are assumed. It is shown that association in the hulk fluid produces different effects on the density profiles at low and high hulk fluid packing fractions. The particle-wall and particle-particle associating interactions are the competitive factors which determine the character of density profiles.
