Thermodynamics, Kinetics and Equilibrium Analysis of Sulphur dioxide Oxidation in a Catalytic Reactor

The research presents sulphur dioxide oxidation from elemental oxygen for a typical study of thermodynamics equilibrium constant of reversible reaction kinetics in a reactor system. A fundamental stoichiometric balanced chemical equation model on the species taking part in the sulphur dioxide SO2 oxidation reaction is applied for the study. Equilibrium compositions of the species involved in the reaction namely; SO3, SO2, O2 with N2 nitrogen gas serving as inert in the reaction process is presented. Consequently, the Van’t equation connecting the equilibrium constant KP of a chemical reaction model is developed and applied for this research. The concentrations of the species are obtained with respect to the number of moles of the species and the partial pressures of the main reaction kinetics. The equilibrium model is achieved on the species by kinetic principles of law of mass action and hence, the equilibrium constant, Kp at the particular temperature of the thermodynamic equilibrium is calculated from the plot approximately 400 K in which depicts the plot of the forward reaction and the reverse reactions of the reversible reaction kinetics of sulphur dioxide oxidation from elemental oxygen. Finally, the studies demonstrate the applications of mass action principles in reversible chemical reactions kinetics.
