Statement -1: The Standard free energy changes of all spontaneously occurring reactions are negative .
Statement-2: The standard free energies of the elements in their standard states at 1 bar and 2985K aare taken aszero.

Options

A. If both the statements are TRUE and STATEMENT-2 is the correct explanation of STATEMENT-8
B. If both the statements are TRUE but STATEMENT-2 is NOT the correct explanation of STATEMENT-8
C. If STATEMENT-1 is TRUE and STATEMENT-2 is FALSE
D. If STATEMENT-1 is FALSE and STATEMENT-2 is TRUE

Answer

To analyze the given statements, we will evaluate each one separately and then determine their relationship.

### Step 1: Evaluate Statement 1
**Statement 1:** The Standard free energy changes of all spontaneously occurring reactions are negative.

**Explanation:**
- The standard free energy change (ΔG°) for a reaction indicates the spontaneity of that reaction.
- For a reaction to be spontaneous at constant temperature and pressure, the change in free energy must be negative (ΔG° < 0).
- Therefore, Statement 1 is **correct**.

### Step 2: Evaluate Statement 2
**Statement 2:** The standard free energies of the elements in their standard states at 1 bar and 298 K are taken as zero.

**Explanation:**
- By definition, the standard free energy of formation of any element in its standard state is defined to be zero.
- This is a convention used in thermodynamics to provide a reference point for calculating the free energy changes of reactions.
- Therefore, Statement 2 is also **correct**.

### Step 3: Determine the Relationship Between the Statements
- Both statements are correct, but they refer to different aspects of thermodynamics.
- Statement 1 discusses the condition for spontaneity of reactions, while Statement 2 provides a reference point for standard free energies.
- Thus, while both statements are true, Statement 2 does not explain Statement 1.

### Conclusion
- Both Statement 1 and Statement 2 are correct, but Statement 2 is not a correct explanation for Statement 1.

### Final Answer:
- **Statement 1 is correct.**
- **Statement 2 is correct.**
- **Statement 2 does not explain Statement 1.**
