### Standard Gibbs Free Energy Changes for ReactionsThe table below presents the standard Gibbs free energy changes (ΔG°) for five different reactions, denoted as reactions A through E. The Gibbs free energy change is an important thermodynamic quantity that helps determine the spontaneity of a reaction. | **Reaction** | **ΔG° (kJ/mol)** ||--------------|------------------|| A | -31.5 || B | -16 || C | -35.6 || D | +6 || E | +26.3 |The ΔG° values provided indicate the amount of energy change for each reaction under standard conditions:- Negative ΔG° values (less than 0) suggest that the reactions (A, B, and C) are spontaneous under standard conditions.- Positive ΔG° values (greater than 0) suggest that the reactions (D and E) are non-spontaneous under standard conditions.The question posed is, "Of these reactions, which is the furthest from chemical equilibrium?"### Answer ExplanationChemical equilibrium is reached when the Gibbs free energy change, ΔG, is zero. This is a state where the forward and reverse reactions occur at the same rate. The reaction that is furthest from equilibrium will have the largest ΔG° value, either positive or negative.In this context, reaction **C** has the most negative ΔG° value (-35.6 kJ/mol), indicating it is the furthest from chemical equilibrium among the given reactions because it is the most spontaneous reaction under standard conditions.Therefore, the correct option is:- [x] **C**- [ ] A- [ ] B- [ ] D

Question

### Standard Gibbs Free Energy Changes for Reactions

The table below presents the standard Gibbs free energy changes (ΔG°) for five different reactions, denoted as reactions A through E. The Gibbs free energy change is an important thermodynamic quantity that helps determine the spontaneity of a reaction.

| **Reaction** | **ΔG° (kJ/mol)** |
|--------------|------------------|
| A | -31.5 |
| B | -16 |
| C | -35.6 |
| D | +6 |
| E | +26.3 |

The ΔG° values provided indicate the amount of energy change for each reaction under standard conditions:

- Negative ΔG° values (less than 0) suggest that the reactions (A, B, and C) are spontaneous under standard conditions.
- Positive ΔG° values (greater than 0) suggest that the reactions (D and E) are non-spontaneous under standard conditions.

The question posed is, "Of these reactions, which is the furthest from chemical equilibrium?"

### Answer Explanation
Chemical equilibrium is reached when the Gibbs free energy change, ΔG, is zero. This is a state where the forward and reverse reactions occur at the same rate. The reaction that is furthest from equilibrium will have the largest ΔG° value, either positive or negative.

In this context, reaction **C** has the most negative ΔG° value (-35.6 kJ/mol), indicating it is the furthest from chemical equilibrium among the given reactions because it is the most spontaneous reaction under standard conditions.

Therefore, the correct option is:
- [x] **C**
- [ ] A
- [ ] B
- [ ] D
