        Sulfur is burnt in air to form sulfur dioxide
        
        S + O2 -> SO2
        
        Mixed with oxygen to form sulfur trioxide
        
        2SO2(g) + O2(g) ⇌ 2SO3(g)
        
        Reaction between sulfur trioxide and water produces sulfuric acid
        
        SO3 + H2O -> H2SO4
        
        Reaction is to violent to carry out directly
        
        Instead of adding sulfur trioxide directly to water, sulfur trioxide is dissolved in concentrated sulfuric acid to produce oleum
        
        SO3 + H2SO4 -> H2S2O7 (Oleum)
        
        Water is then added to oleum to form sulfuric acid
        
        H2S2O7 + H2O -> 2H2SO4
        
        Conditions required
        
        400-450 Degrees celsius
        
        1-2 atmospheres
        
        Vanadium (V) Oxide catalyst
        
        Process of producing sulfuric acid
