Chem 124 Entropy/Free Energy Worksheet Dr. Meadows 1. Give the five situations that generally result in an increase of entropy. 2. Would you expect the entropy to increase or decrease in each of the following? a. CCl 4 (l) CCl 4 (g) b. CuSO 4 3H 2 O (s) + 2H 2 O (g) CuSO 4 5H 2 O (s) c. SO 3 (g) + H 2 (g) SO 2 (g) + H 2 O (g) d. H 2 (g, 1 atm) H 2 (g, 2 atm) e. C (s, graphite) C (s, diamond) 3. Using the tables of thermodynamic data, calculate the standard molar entropy change ( S ° 298 ) for the synthesis of ammonia gas from its elements: N 2 (g) + 3H 2 (g) 2NH 3 (g) 4. Consider the reaction below and without reference to any data tables, draw the proper conclusion on which condition A-D best represents the reaction being spontaneous as written. CO 2 (g) + H 2 O (g) HCOOH (l) H = -150 kJ A. The reaction would be spontaneous at all temperatures. B.
