For which reaction from the following, will have maximum entropy change?
(a) \( \mathrm{Ca}(\mathrm{s})+\frac{1}{2} \mathrm{O}_{2}(\mathrm{~g}) \rightarrow \mathrm{CaO}(\mathrm{s}) \)
(b) \( \mathrm{CaCO}_{3} \) (s) \( \rightarrow \mathrm{CaO} \) (s) \( +\mathrm{CO}_{2} \) (g)
(c) \( \mathrm{C}(\mathrm{s})+\mathrm{O}_{2}(\mathrm{~g}) \rightarrow \mathrm{CO}_{2} \) (g)
(d) \( \mathrm{N}_{2}(\mathrm{~g})+\mathrm{O}_{2}(\mathrm{~g}) \rightarrow 2 \mathrm{NO}(\mathrm{g}) \)
