The Rayleigh-Benard convection for a chemical equilibrium gas with inert microparticles is considered in the Boussinesq approximation. The convection is shown to develop in accordance to two contradictory tendencies. On the one hand, continuous processes of recombination and dissociation in the gas mixture are responsible for the increase in the thermal extension coefficient, which decreases the critical Rayleigh number and leads to intensified convection. On the other hand, chemically inert microparticles in the gas mixture cause increased thermal diffusivity and, as a result, the critical Rayleigh number grows while the convection rate decreases with corresponding decreasing of Nusselt number and rms of temperature value.
