32. Solving a chemistry problem

59. The following reactions are used to produce sulfuric acid:

ΔН0, kJ/mol ΔS0 ΔG0, kJ/mol
S(c) O2(g)=SO2(g) -70.9 2.7 -71.7
SO2(g) 1/2O2(g)=SO3(g) -23.7 -22.5 -17.0
SO3 H2O(l)=H2SO4(l) -35.4 -73.2 -32.5

What can you say about the energy sustainability of SO2 and SO3.
