# Problem: For which of the following processes would you expect there to be an increase in entropy? Ag+(aq) + Cl–(aq) → AgCl(s) H2O(g) → H2O(l) CaBr2(s) → Ca2+(aq) + 2 Br–(aq) CO2(g) → CO2(s) N2(g) + 3 F2(g) → 2 NF3(g)

We’re being asked to determine the processes that would you expect there to be an increase in entropy. Recall that if:

• ΔS > 0 or ΔS = (+); entropy is increased

• ΔS < 0 or ΔS = (–); entropy is decreased

Remember that phase changes lead to a change in entropy: Also, recall that an increase in the number of gas molecules in the reaction also leads to an increase in entropy.

For which of the following processes would you expect there to be an increase in entropy?

Ag+(aq) + Cl(aq) → AgCl(s)

H2O(g) → H2O(l)

CaBr2(s) → Ca2+(aq) + 2 Br(aq)

CO2(g) → CO2(s)

N2(g) + 3 F2(g) → 2 NF3(g)
