This is extra practice for exam 4.  Don’t worry about the free energy problems (prob 5 and 7).  Focus on entropy problems (prob 1 – 4, 8, and 9).  Working on this will pay off also for the  second thermo homework. Prob 1 Predict the sign of the entropy change of the system for each of the following reactions. (a)     (-) (b)     (+) (c)     (-) (d)     (+) Prob 2 Which Has Higher S? A   or  ,   Ar(g) B  1 mol  at 3 atm pressure or 1 mol  at 1.5 atm pressure,   1 mol He(g) at 1.5 atm C  1  of  in 15.0  or 1  of  in 1.50  ,   Ne in 15.0 L D   or  .  CO 2 (g) Prob 3 How does the entropy of the system change when a solid melts, a gas liquefies, a solid  sublimes? Solid Melts:  ΔS > 0 Gas Liquified:  ΔS < 0 Solid Sublines:   ΔS > 0 Prob 4 Part A  Predict the sign of the entropy change,  , for each of the following reactions.
