The Contact Process describes the industrial synthesis of sulfuric acid via a reversible, exothermic oxidation reaction converting sulfur dioxide to sulfur trioxide over a heterogeneous vanadium pentoxide catalyst. The theoretical framework necessitates specific purification and drying stages prior to reaction to maintain catalyst integrity while adhering to thermodynamic constraints that limit conversion efficiency at high temperatures due to Le Chatelier's principle. This mechanism is defined within the domain of chemical engineering kinetics, balancing equilibrium yields against operational temperature limits to produce oleum for subsequent controlled dilution into concentrated sulfuric acid.
