Carbon monoxide is more effective reducing agent than carbon below `983 K` but above this temperature, the reverse is true. How would you explain this ?

Explanation

To explain why carbon monoxide (CO) is a more effective reducing agent than carbon (C) below 983 K, but the reverse is true above this temperature, we can analyze the thermodynamics of the reactions involved.

### Step-by-Step Solution:

1. **Understanding Reducing Agents:**
- A reducing agent is a substance that donates electrons to another substance, causing the other substance to be reduced. The effectiveness of a reducing agent is often determined by its Gibbs free energy change (ΔG) during the reaction.

2. **Reactions Involved:**
