A quantum kinetical equation for the one‐particle density operator for inhomogeneous multi component non‐ideal gases is derived taking into account retardation effects and external fields. It is shown that the interactions give rise to additional contributions to the quantities in the transport equation. In some terms (e.g., internal energy, pressure, effective external force) the interaction effects are strong in the presence of bound states and yield contributions of the order exp (— E 10 / kT ) where E 10 is the ground state energy of bound pairs of particles. Other terms (e.g. friction forces) are rather insensitive with respect to the presence of bound states. An interpretation of these effects in terms of the mass action law is given using the principle of equivalence between bound states and particles.
