Predict which of the following reaction (s) has a positive entropy change?
I. \( \mathrm{Ag}^{+}(\mathrm{aq})+\mathrm{Cl}^{-}(\mathrm{aq}) \longrightarrow \mathrm{AgCl}(\mathrm{s}) \)
II. \( \mathrm{NH}_{4} \mathrm{Cl}(\mathrm{s}) \longrightarrow \mathrm{NH}_{3}(\mathrm{~g})+\mathrm{HCl}(\mathrm{g}) \)
III. \( 2 \mathrm{NH}_{3}(\mathrm{~g}) \longrightarrow \mathrm{N}_{2}(\mathrm{~g})+3 \mathrm{H}_{2}(\mathrm{~g}) \)
(a) I and II
(b) III
(c) II and III
(d) II
