Question
  1. a) Calculate the standard free energy of formation for ozone at 298oK from the values of ΔHof and So given in Tables.

The formation reaction is

3/2O2(g) → O3(g)

Note: You can find these values (ΔHof and So) in the Tables using the internet.

  1. b) Calculate ΔGo and K for the reaction;

NO + O3 → NO2 + O2

Is the size of the equilibrium constant principally a consequence of the ΔHo or of the ΔSo for this reaction?

Note: You can find all values of ΔGof, ΔSo and ΔHof regarding molecules in the Tables using the internet.
