Which of the following reactions will have the value of \( \Delta S \) with a negative sign?
(a) \( \mathrm{H}_{2} \mathrm{O}(l) \longrightarrow \mathrm{H}_{2} \mathrm{O}(g) \)
(b) \( 2 \mathrm{SO}_{2}(g)+\mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{SO}_{3}(g) \)
(c) \( \mathrm{Cl}_{2}(g) \longrightarrow 2 \mathrm{Cl}(g) \)
(d) \( \mathrm{CaCO}_{3}(s) \longrightarrow \mathrm{CaO}(s)+\mathrm{CO}_{2}(g) \)
