Which reaction has the greatest increase in entropy?

A.     \({\text{S}}{{\text{O}}_2}{\text{(g)}} + {\text{2}}{{\text{H}}_2}{\text{S(g)}} \to {\text{2}}{{\text{H}}_2}{\text{O(l)}} + {\text{3S(s)}}\)

B.     \({\text{CaO(s)}} + {\text{C}}{{\text{O}}_2}{\text{(g)}} \to {\text{CaC}}{{\text{O}}_3}{\text{(s)}}\)

C.     \({\text{Ca}}{{\text{C}}_2}{\text{(s)}} + {\text{2}}{{\text{H}}_2}{\text{O(l)}} \to {\text{Ca(OH}}{{\text{)}}_2}{\text{(s)}} + {{\text{C}}_2}{{\text{H}}_2}{\text{(g)}}\)

D.     \({{\text{N}}_2}{\text{(g)}} + {{\text{O}}_2}{\text{(g)}} \to {\text{2NO(g)}}\)
