Slip boundary conditions are deduced for the Navier-Stokes equations describing the flow of a mixture of gases along a wall. Chemical reactions and changes of the internal energy at the wall are taken into account. A simplified approximation is introduced for a special case of the flow of a binary mixture consisting of atoms and molecules, which can be used as a model in treating the high-altitude flight of a space vehicle. The resulting conditions are compared with those given by other authors.
