Part A Define the second law of thermodynamics. For any spontaneous process, the entropy of the universe decreases (AS universe <0). For any nonspontaneous process, the entropy of the universe decreases (AS universe <0). The entropy of a perfect crystal at absolute zero (0 K) is zero. For any spontaneous process, the entropy of the universe increases (AS universe > 0). For any nonspontaneous process, the entropy of the universe increases (AS universe > 0).

Transcribed Image Text:Part A
Which of the following processes has a ASsys > 0?
OCH4(g) + H₂O(g) → CO(g) + 3 H₂(g)
CO₂(1)→ CO₂ (s)
Li₂CO3(s) + H₂O(g) + CO₂(g) → 2 LIHCO3(s)
N₂(g) + 3 H₂(g) → 2 NH3(g)
All of the above processes have a AS > 0.
