![**Thermochemistry Calculation: Formation of HI**
**Reaction Overview:**
HI (hydrogen iodide) is formed from the reaction of H₂ (hydrogen gas) and I₂ (iodine gas) as shown in the equation:
\[ \text{H}_2(g) + \text{I}_2(g) \rightarrow 2\text{HI}(g) \]
**Part 1 out of 2:**
Use the following thermochemical data to calculate \( \Delta G^\circ_{\text{rxn}} \) for the formation of HI at 25°C.
**Thermochemical Data Table:**
| | H₂(g) | I₂(g) | HI(g) |
|----------------|-------|-------|--------|
| \( \Delta H^\circ_f \) (kJ/mol) | 0 | 62.25 | 25.9 |
| \( \Delta S^\circ_f \) (J/mol) | 131 | 260.57| 206.3 |
**Calculation:**
Calculate \( \Delta G^\circ_{\text{rxn}} \) using the formula:
\[ \Delta G^\circ_{\text{rxn}} = \Delta H^\circ_{\text{rxn}} - T \Delta S^\circ_{\text{rxn}} \]
*Note: Ensure to convert all values to consistent units before computing.*
**Result:**
\[ \Delta G^\circ_{\text{rxn}} = \text{[Insert calculated value]} \, \text{kJ/mol} \]
