Which of the processes represented by the following equations has the greatest positive entropy change?

A.

C6H3(l) → C6H 6 (g)

B.

H2O (s) → H2O(l)

C.

CuO(s) + H2(g) → Cu(s) + H2

D.

Na2CO3(s) + nH2O(l) →Na 2CO3nH2O(s)

E.

S(s) → S(l)

Correct answer is A

we have the greatest entropy when a substance changes from the liquid phase to the gaseous phase this is because the particles of gases are very loosely packed so they have the freedom to move around.
