Solution: Consider the following reactions at 25°C: Reaction                                                           Kc 2 NO (g) ⇌ N2 (g) + O2 (g)                           1 × 10   30 2 H2O (g) ⇌ 2 H2 (g) +

Problem

Consider the following reactions at 25°C:
Reaction                                                           Kc
2 NO (g) ⇌ N(g) + O(g)                           1 × 10   30
2 H2O (g) ⇌ 2 H(g) + O(g)                       5 × 10   −82
2 CO (g) + O(g) ⇌ 2 CO(g)                      3 × 10   91


Which compound is most likely to dissociate and give O(g) at 25°C?

1. CO2

2. NO

3. CO

4. H2O
