The following balanced reactions occur under standard conditions (298 K, 1 atm).
Reaction I: 2 KClO₃(s) → 2 KCl(s) + 3 O₂(g)
Reaction II: N₂(g) + 3 H₂(g) → 2 NH₃(g)
Reaction III: C₆H₁₂O₆(s) → 2 C₂H₅OH(l) + 2 CO₂(g)
(1) (a) Predict and justify the sign of ΔS° for Reaction I.
(2) (a) Predict and justify the sign of ΔS° for Reaction II.
(3) (a) Predict and justify the sign of ΔS° for Reaction III.
(4) (b) Rank Reactions I–III from largest positive to most negative ΔS°, with justification.
