Include physical states and represent graphite as C(s).**Answer:**\[ \text{chemical equation:} \]\[ \boxed{\text{MO}_2 (s) + \text{C} (s) \rightleftharpoons \text{M} (s) + \text{CO}_2 (g)} \]**Question 2: Thermodynamic Equilibrium Constant**What is the thermodynamic equilibrium constant for the coupled reaction?**Answer:**\[ K = \boxed{} \]**Explanation:**When exploring the equilibrium and thermodynamics of reactions, combining exergonic (energy-releasing) and endergonic (energy-absorbing) reactions can drive the overall process to be spontaneous. The given reaction demonstrates this principle by coupling the metal oxide decomposition with graphite oxidation, thus enabling the reaction to proceed spontaneously. The problem aims to showcase these thermodynamic principles in action.
