The oxidation of SO₂ is the key step in sulfuric acid production: SO₂ (g) + 1/2O2(g) → SO3 (g) AHx= -99.2 kJ/mol a. To maximize the production of SO3, should there be high pressure or low pressure in the reaction chamber? Explain your answer in terms of Le Châtelier's Principle. b. To maximize the production of SO3, should there be high temperature or low temperature in the reaction chamber? Explain your answer in terms of Le Châtelier's Principle. c. If O₂ is added to the reaction chamber, how will the reaction respond? Ỏ. The reaction is catalyzed by vanadium oxide. If this is added to the reaction chamber, in which direction does the reaction shift?
