Problem

Which of the following processes involves a decrease in entropy?

a. the decomposition of NH 3 (g)

b. the condensation of steam

c. the sublimation of CO2 

d. the evaporation of ethanol

e. the dissolution of NH4NO3(s) in water

f.  I2 at 90oC and 5.0 atm  →  I2 at 50oC and 10.0 atm

g. NH4Cl(s) → HCl(g) +  NH3(g)

h. CH4(g)  +  2 O2(g)  →  CO2(g)  +  2 H2O(l)
