a. there is no change in entropy
b. the entropy is most likely negative because the molecules in the solid state are more random than the molecules in the gaseous state.
c. the entropy decreases and the sign of /\S most likely would be negative.
d. /\S most likely would be positive because a gas has greater entropy than a solid.

(the /\ is suppose to be a triangle)

d. is the answer that is closest to being correct.

The *molar* entropy of a substance in the gas phase is always greater than the molar entropy of that substance as a solid.
