For which of the following processes would ΔS° be expected to be most positive? A)H₂O(l)→ H₂O(s) B)NH₃(g)+ HCl(g)→ NH₄Cl(s) C)O₂(g)+ 2H₂(g)→ 2H₂O(g) D)N₂O₄(g)→ 2NO₂(g) E)2NH₄NO₃(s)→ 2N₂(g)+ O₂(g)+ 4H₂O(g)

The process with the most positive ΔS° is typically the one that results in the greatest increase in the number of gas molecules, indicating a transition from a more ordered state to a less ordered state. Option E involves the production of 7 gas molecules from solid reactants, which represents a significant increase in disorder and hence, a positive ΔS°.
