### Question:
What can you conclude about \( \Delta G^\circ_{\text{rxn}} \) for the reaction?

### Options:
- \( \Delta G^\circ_{\text{rxn}} = 0 \)
- \( \Delta G^\circ_{\text{rxn}} > 0 \)
- \( \Delta G^\circ_{\text{rxn}} < 0 \)

### Explanation:
The question asks you to determine the standard Gibbs free energy change (\( \Delta G^\circ_{\text{rxn}} \)) for a given chemical reaction. Understanding the sign and magnitude of \( \Delta G^\circ_{\text{rxn}} \) can help predict the spontaneity of the reaction:

- \( \Delta G^\circ_{\text{rxn}} = 0 \): The reaction is at equilibrium.
- \( \Delta G^\circ_{\text{rxn}} > 0 \): The reaction is non-spontaneous under standard conditions.
- \( \Delta G^\circ_{\text{rxn}} < 0 \): The reaction is spontaneous under standard conditions.

The diagram is a simple multiple-choice question with three options presented in a box. Select the one that applies to the reaction in question.
