Coke can be used to reduce `Cu_(2)O`. Explain it based on thermodynamic view.

Explanation

To explain how coke (carbon) can be used to reduce cuprous oxide (Cu₂O) based on a thermodynamic view, we can break down the process into several steps:

### Step 1: Understanding the Reduction Reaction
The reduction of cuprous oxide (Cu₂O) to copper (Cu) can be represented by the following reaction:
\[ \text{Cu}_2\text{O} + \text{e}^- \rightarrow 2\text{Cu} + \text{O}^{2-} \]

### Step 2: Analyzing the Gibbs Free Energy Change
The Gibbs free energy change (ΔG) for the reduction of Cu₂O is positive, indicating that this reaction is non-spontaneous under standard conditions. A positive ΔG means that the reaction does not occur naturally without the input of energy.
