Equilibrium composition and initial rate of the reversible solid phase reaction in the system Na2CO3-BaSO4-Na2SO4-BaCO3

The results of experimental study of reversible solid-state reaction Na 2 CO 3 + BaSO 4 = Na 2 SO 4 + BaCO 3 were considered. The equilibrium composition of the mixture at 550 and 600°C with 10 different initial ratios of the reactants, and the initial rate of the process were determined. The role o...

Description
Summary:The results of experimental study of reversible solid-state reaction Na 2 CO 3 + BaSO 4 = Na 2 SO 4 + BaCO 3 were considered. The equilibrium composition of the mixture at 550 and 600°C with 10 different initial ratios of the reactants, and the initial rate of the process were determined. The role of the Le Chatelier principle in the analysis of the thermodynamic state of the reagents was considered. The thermodynamic equilibrium constant was found from the data on the dependence of concentration equilibrium constants on the composition and the results of X-ray phase analysis using regular solution theory.
