Which is a better reducing agent at `710^@ C : C` or `CO` ?

Explanation

To determine which is a better reducing agent at 710°C, carbon (C) or carbon monoxide (CO), we can analyze the reactions and their thermodynamic favorability based on the Gibbs free energy change (ΔG).

### Step-by-Step Solution:

1. **Understand the Reactions**:
- Carbon reacts with oxygen to form carbon dioxide (CO₂).
- Carbon can also react with oxygen to form carbon monoxide (CO).
- Carbon monoxide can react with oxygen to form carbon dioxide (CO₂).
