    From the reaction;

    2SO2 (g) + O2 (g) = 2SO3 (g) + 394 kJ

    In the reaction a mixture of plantinum and vanadium (V) oxide may be used as a catalyst for the reaction. The sulfur trioxide produced is then used to make sulfuric acid.

    The energy that is required to release 1 mole of sulfur trioxide is + 394 joules

    For one mole of sulfur trioxide;

    the energy that will be released will be 394/2 = 197 kJ

    Thus; the amount of energy released is + 197 kJ
