202-NYB-05: Course Notes ProblemsChapter 6: Thermochemistry. (Zumdahl/Zumdahl, 10th Ed)
Problem 1: Calculate E for a system undergoing an endothermic process in
which 15.6 kJ of heat flows and where 1.4 kJ of work is done on the system.
Problem 2: Calculate the work associated with the expansion of a gas from 46 L
to 64 L at a constant external pressure of 15 atm.
Chapter 17: Spontaneity, Entropy, and Free Energy.
Problem 1: Predict the sign of the entropy change (S) for each of the following
processes.
a) Solid sugar is added to water to form a solution.
b) Iodine vapor condenses on a cold surface to form crystals.
c) Freezing point (liquid to solid).
d) Sublimation (solid to gas)
Problem 2: Calculate Ssurr for the following reactions at 25o C and 1 atm.
a) Sb2S3 (s) + 3 Fe (s) 2 Sb (s) + 3 FeS (s) H = -125 kJ
b) Sb4O6 (s) + 6 C (s) 4 Sb (s) + 6 CO (g) H = 778 kJ
Problem 3: Predict the sign of So for each of the following reactions.
a) CaCO3 (s) CaO (s) + CO2 (g)
b) 2 SO2 (g) + O2 (g) 2 SO3 (g)
