For Question 3!

1: Above what temperature does the following reaction become
nonspontaneous?
FeO(s) + CO(g) → CO₂(g) + Fe(s) AH = -11.0 kJ; AS = -17.4 J/K
2: Find AS surr and predict whether or not this reaction will be
spontaneous at 398 K.
NH3(g) + O₂(g) → N₂(g) + H₂O(g) AH = -1267 kJ
3: Which one of the following has the highest standard molar
entropy, Sº, at 25°C and why?
a: F₂ (g) b: Cl₂ (g) c: N₂ (g) d: O₂ (g) e: H₂(g)
