Text Solution

AI Generated Solution

To determine which reactions involve homogeneous equilibria and which involve heterogeneous equilibria, we need to analyze the phases of the reactants and products in each reaction. ### Step-by-Step Solution: 1. **Identify the Phases of Each Reaction:** - **a)** `2N₂O(g) ⇌ 2N₂(g) + O₂(g)` - All species are gases. - **b)** `2NH₃(g) ⇌ N₂(g) + 3H₂(g)` ...
