We will present a model of motion of compressible mixture of chemically reacting species. We study a general form of diffusion deriving forces in which the variation of total pressure is taken into account. We will discuss sequential stability of weak solutions and present the proof of global in time existence of weak solutions without any restriction on the size of data. This result is based on several joint papers with P.B. Mucha and M. Pokorn ́y.
