The possibility of the unified description of kinetic, hydrodynamic and reaction diffusion processes is considered. The generalized kinetic equation consists of three dissipative “collision integrals”: 1 The “collision integral” defined by processes of “collisions” in velocity space 2 The dissipative term of the diffusion type in the coordinate space 3 The dissipative term in the space of the electron concentration n e defined by the ionization — recombination reaction in a plasma This equation can be used for the description of nonequilibrium processes of partially ionized plasmas for all values of Knudsen's number.
