11. For each pair of substances determine which has the higher entropy per mole of substance. a. H2O (s) at 200 K or H2O(s) at 298 K. b. H2(g) at 298 K, 2.0 atm or H2(g) at 298 K, 1.0 atm. c. H2(g) at 298 K, 5.0 L or H2(g) at 298 K, 1.0 L. d. H2(g) at 500 K, 1.0 atm or H2(g) at 298 K, 1.0 atm. e. H2O(l) at 298 K or H2O(g) at 298 K. f. O2(g) at 298 K, 1.0 atm or N2O4(g) at 298 K, 1.0 atm.
Answer: H2O(s) at 298 K
Reason: Increasing the temperature will increase the entropy
Answer: H2(g) at 298 K, 1.0 atm.
Reason: A gas has higher entropy at a lower pressure.
Answer: H2(g) at 298 K, 5.0 L
Reason: The larger the volume the higher the entropy.
Answer: H2(g) at 500 K, 1.0 atm
Reason: Increasing the temperature will increase the entropy
Answer: H2O(g) at 298 K.
Reason: A gas has higher entropy than a liquid.
Answer: N2O4(g) at 298 K, 1.0 atm
Reason: More will be the gaseous components more will be entropy
