**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
