Base your answer to the questions on the information below and on your knowledge of chemistry. One process used to manufacture sulfuric acid is called the contact process. One step in this process, the reaction between sulfur dioxide and oxygen, is
represented by the forward reaction in the system at equilibrium shown below.
2SO2(g) +O2(g) = 2SO3(g) + 394 kJ
A mixture of platinum and vanadium(V) oxide may be used as a catalyst for this reaction. The sulfur trioxide produced is then used to make sulfuric acid.
Determine the amount of energy released when 1.00 mole of sulfur trioxide
produced
