5. An important step in the contact process for the manufacture of sulfuric acid is the catalyzed reaction between sulfur dioxide and oxygen to form sulfur trioxide. This is a homogeneous gaseous reaction that is exothermic. a) Write the chemical equation for this step, showing the sign of AH. (Value: 2 marks) b) Describe three changes that would increase the yield of sulfur trioxide. (Value: 3 marks)
