Question

Which of the following changes has a decrease in entropy?
Answer







C2H5OH (l) + 3O2 (g) 2CO2 (g) + 3 H2O (g)








N2O4 (g) 2NO2 (g)








C6H6 (l) C6H6 (s)








2LiClO3 (s) 3O2 (g) + 2LiCl (s)

Answer 1

Here is the question

Answer 2

entropy will be decrease in this reaction:
C6H6 (l) -> C6H6 (s)
cause entropy is a measure of disorder and by becoming solid matter reduces entropy
