Question
Classify the following as homogeneous or heterogeneous equilibria:
  1. $2\text{SO}_2(\text{g})+\text{O}_2(\text{g})\rightleftharpoons2\text{SO}_3(\text{g})$
  2. $2\text{Mg(s)}+\text{O}_2(\text{g})\rightleftharpoons2\text{MgO(s)}$
✓

Answer

  1. Homogeneous equilibria because all reactant and products are gases.
  2. Heterogeneous equilibria because Mg and MgC are solid whereas O2 is gas.
