Question

Can someone check my work?
"Which of the following changes will always be true for a system with increasing entropy?"
I put +deltoid S.
"Which of the following changes has a decrease in entropy?"
The answer choices are:
N2O4 (g) => 2NO2 (g)
C6H6 (l) => C6H6 (g)
2LiClO3 (s) => 3O2 (g) + 2LiCl (s)
3Fe (s) + 2O2 (g) => Fe3O4 (g)
I put the last choice as the answer.

Answer 1

the 2nd is right, and so is the first.. but you're basically saying "what will be true for a system with increasing entropy? change in entropy is positive" which is kinda redundant.
