Artigo:

In this work, we consider a dilute reactive mixture of four constituents undergoing the reversible reaction A+B C+D. The mixture is described using the Boltzmann equation (BE) to chemically reactive systems which treats both elastic and reactive collisions as hard spheres type. We use the Chapman-Enskog method, at the first-order level of the Enskog expansion, to determine the non-equilibrium solution to the system in a chemical regime for which both elastic and reactive collisions occur with comparable characteristic times. In this case, the chemical reaction can be considered in its final stage, close to chemical equilibrium (fast process). We then determine the transport coefficients and focus our analysis on the evaluation of the coefficient associated with the shear viscosity and investigate how the reaction heat and the activation energy changes this coefficient.
