**Thermodynamic Properties Table** | Substance | \( \Delta H_f^\circ \) (kJ/mol) | \( G^\circ \) (kJ/mol) | \( S^\circ \) (J/mol·K) | |-----------|--------------------|------------------|------------------| | \( P_2 \) (g) | 144.3 | -- | 216.1 | | \( PCl_3 \) (g) | -288.1 | -- | 311.7 | | \( POCl_3 \) (g) | -542.2 | -- | 325 | | \( Cl_2 \) (g) | 0 | 0 | 222.96 | | \( O_2 \) (g) | 0 | 0 | 205.0 | | \( H_2O \) (l) | -285.83 | -- | 69.91 | **Explanation:** This table presents the thermodynamic properties of various substances. It includes: - **Standard Enthalpy of Formation (\( \Delta H_f^\circ \))**: Measured in kJ/mol, it indicates the heat change when one mole of a compound is formed from its elements at standard conditions. - **Standard Gibbs Free Energy (\( G^\circ \))**: Typically provided in kJ/mol, it is the energy associated with a chemical reaction that can be used to do work at standard conditions. In this table, the values are not provided. - **Standard Entropy (\( S^\circ \))**: Given in J/mol·K, it represents the degree of disorder or randomness in the system. The table includes substances such as phosphorus (\( P_2 \)), phosphorus trichloride (\( PCl_3 \)), phosphorus oxychloride (\( POCl_3 \)), chlorine (\( Cl_2 \)), oxygen (\( O_2 \)), and water (\( H_2O \)).

The given image contains a handwritten chemistry question related to Gibbs free energy change (ΔG°) at 25°C. The question asks for the ΔG° value for the formation of phosphorus trichloride from its constituent elements. The reaction is: \[ \text{P}_2(g) + 3\text{Cl}_2(g) \rightarrow 2\text{PCl}_3(g) \] It asks to fill in the blank with the correct value of ΔG° in kJ/mol. The options are: A) -589.2 B) +539.2 C) -373.3 D) +642.9 E) -642.9
