Formation of Sulfur Trioxide
An important process in the industrial production of sulfuric acid and in the formation of acid rain. We will use enthaplies of reactions to study the energy involved in this process.
S (s) + O2 (g) ----> SO2 (g) DH1 = -296.8 kJ
2SO2(g) + O2(g) ----> 2SO3 (g) DH2 = -198.4 kJ
S(s) + (3/2)O2(g) ---> SO3(g) DH3 = ?
