**Thermodynamics of the Reaction**

**ΔG° for the Reaction:**

\[ \text{H}_2(g) + \text{I}_2(g) \rightleftharpoons 2\text{HI}(g) \]

- **ΔG°**: 2.60 kJ/mol at 25°C

**Initial Conditions of the Experiment:**

- \( P_{\text{H}_2} = 4.06 \, \text{atm} \)
- \( P_{\text{I}_2} = 0.022 \, \text{atm} \)
- \( P_{\text{HI}} = 0.47 \, \text{atm} \)

**Task:**

Calculate ΔG for the reaction and determine the direction of the net reaction.

- **Box for Calculated ΔG:** ___ kJ/mol

**Decide on Net Reaction Direction:**

- ( ) The net reaction proceeds from left to right
- ( ) The reaction proceeds from right to left
