Which process would be expected to have a $\Delta {S^\Theta }$ value which is negative?

A.     ${\text{2}}{{\text{H}}_2}{\text{(g)}} + {{\text{O}}_2}{\text{(g)}} \to {\text{2}}{{\text{H}}_2}{\text{O(g)}}$

B.     ${\text{NaCl(s)}} \to {\text{N}}{{\text{a}}^ + }{\text{(g)}} + {\text{C}}{{\text{l}}^ - }{\text{(g)}}$

C.     ${{\text{H}}_2}{\text{(g)}} + {{\text{I}}_2}{\text{(g)}} \to {\text{2HI(g)}}$

D.     ${\text{O}}{{\text{F}}_2}{\text{(g)}} + {{\text{H}}_2}{\text{O(g)}} \to {{\text{O}}_2}{\text{(g)}} + {\text{2HF(g)}}$
