For each of the following questions, refer to the following balanced equation and the Data Table above. Give your answers to the first decimal place if the answer is greater than 1. Otherwise, use exponential format (e.g. 1.23E-10)

\[ 2 \, \text{HgO}_{(s)} = 2 \, \text{Hg}_{(l)} + \text{O}_{2(g)} \]

a) Determine the value of \( \Delta G^\circ_{\text{rxn}} \) at 350 K, based on moles of \( \text{O}_2 \). Do not include the units in the answer and assume that \( \Delta H^\circ_{\text{rxn}} \) and \( \Delta S^\circ_{\text{rxn}} \) do not change considerably with temperature.

[Input box] kJ/mole

b) Determine the value of \( K_{\text{eq}} \) (3 significant figures) at 350 K.

c) At 400 °C would you make more or less product than at 350 °C? Enter either more or less in lowercase.

### Thermodynamic Data Table

Use the following data table to answer the questions:

#### Data Table

| Substance | \( H_f^\circ \) (kJ/mole) | \( S_f^\circ \) (J/mole·K) | \( G_f^\circ \) (kJ/mole) |
|-----------|----------------|----------------|-----------------|
| \( \text{Hg}_{(l)} \) | 0 | 76.0 | 0 |
| \( \text{Hg}_{(g)} \) | 61.3 | 174.9 | 31.8 |
| \( \text{HgO}_{(s)} \) | -90.8 | 70.3 | -58.5 |
| \( \text{O}_2_{(g)} \) | 0 | 205.0 | 0 |

### Explanation
 
- **\( H_f^\circ \) (kJ/mole):** Enthalpy of formation at standard conditions.
- **\( S_f^\circ \) (J/mole·K):** Entropy at standard conditions.
- **\( G_f^\circ \) (kJ/mole):** Gibbs free energy of formation at standard conditions.

This data table provides thermodynamic values for different substances in various phases. It includes enthalpy, entropy, and Gibbs free energy for liquid mercury \(\text{Hg}_{(l)}\), gaseous mercury \(\text{Hg}_{(g)}\), solid mercury(II) oxide \(\text{HgO}_{(s)}\), and gaseous oxygen \(\text{O}_2_{(g)}\). 

This can be used to calculate reaction enthalpies, entropies, and Gibbs free energies for chemical reactions involving these substances.
