Question

Which of the following changes has a decrease in entropy?

2LiClO3 (s) yields 3O2 (g) + 2LiCl (s)
N2O4 (g) yields 2NO2 (g)
C6H6 (l) yields C6H6 (s)
C2H5OH (l) + 3O2 (g) yields 2CO2 (g) + 3 H2O (g)

Answer 2

A decrease in entropy is an increase in order. Liquids are more disordered than solids.
