Question:

Without doing a calculation, predict whether the entropy change will be positive or negative when each of the following reactions occurs in the direction it is written.
(a) CH₃OH(ℓ) + 3/2 O₂(g) → CO₂(g) + 2 H₂O(g)
(b) Br₂(ℓ) + H₂(g) → 2 HBr(g)
(c) Na(s) + 1/2 F₂(g) → NaF(s)
(d) CO(g) + 2 H₂(g) → CH₃OH(ℓ)
(e) 2 NH₃(g) → N₂(g) + 3 H₂(g)
