For which of the following process Δ S° is positive?
Options:(select one or more)
Answer:
A, B, C
Solution:
Dissolving a crystalline solid into ions in solution increases disorder; gas expansion increases the number of accessible positions; 2 HgO(s) → 2 Hg(l) + O2(g) produces a gas. Rusting of iron consumes O2 gas to form a solid, so Δ S < 0. Ans: (a), (b), (c).
