Question
Transcribed Image Text:For each of the reactions at constant pressure, determine whether the system does work on the surroundings, the surroundings
does work on the system, or essentially no work is performed.
Work done by the system
N₂(g) + 3 H₂(g) → 2 NH3(g)
2 H₂O₂(g) O₂(g) + 2 H₂O(g)
Work done on the system
Answer Bank
NaHCO3(s) + HC₂H₂O₂ (aq) → NaC₂H₂O₂ (aq) + H₂O(1) + CO₂ (g)
No work done
H₂(g) + F₂(g) →
→ 2 HF(g)
