Question: The change in entropy, Srxn, is related to the change in the number of moles of gas molecules, ngas. Determine the change in the moles

The change in entropy, ΔS°rxn, is related to the change in the number of moles of gas molecules, Δngas. Determine the change in the moles of gas for each of the following reactions and decide if the entropy increases, decreases, or has little or no change.

a) KO₂ (s) --> K (s) + O₂ (g)

b) N₂O_{2 (g)} --> 2NO (g) + O₂ (g)
