  The balance equations for thermodynamic quantities are derived from the
nonlocal quantum kinetic equation. The nonlocal collisions lead to molecular
contributions to the observables and currents. The corresponding correlated
part of the observables is found to be given by the rate to form a molecule
multiplied with its lifetime which can be considered as collision duration.
Explicit expressions of these molecular contributions are given in terms of the
scattering phase shifts. The two-particle form of the entropy is derived. This
extends the Landau quasiparticle picture by two-particle molecular
contributions. There is a continuous exchange of correlations into kinetic
parts condensing into the rate of correlated variables for energy and momentum.
For the entropy, an explicit gain remains and Boltzmann's H-theorem is proved
including the molecular parts of the entropy.
