The weakest oxidizing agent among the following is

Options

A. `O_(3)`
B. `F_(2)`
C. `KMnO_(4)`
D. `Cl_(2)`

Explanation

To find the weakest oxidizing agent among the given options (ozone, fluorine gas, chlorine gas, and chlorine gas), we need to compare their reduction potentials. The higher the reduction potential, the stronger the oxidizing agent. Therefore, the one with the lowest reduction potential will be the weakest oxidizing agent.

### Step-by-Step Solution:

1. **Identify the Species and Their Reduction Reactions**:
- Ozone (O₃) is reduced to oxygen (O₂).
- Fluorine gas (F₂) is reduced to fluoride ions (F⁻).
- Chlorine gas (Cl₂) is reduced to chloride ions (Cl⁻).

2. **List the Reduction Potentials**:
- For ozone (O₃ → O₂), the reduction potential (E°) is **2.07 V**.
- For fluorine (F₂ → 2F⁻), the reduction potential (E°) is **2.87 V**.
- For chlorine (Cl₂ → 2Cl⁻), the reduction potential (E°) is **1.36 V**.

3. **Compare the Reduction Potentials**:
- Ozone: 2.07 V
- Fluorine: 2.87 V
- Chlorine: 1.36 V

4. **Determine the Weakest Oxidizing Agent**:
- Among the listed reduction potentials, **chlorine (1.36 V)** has the lowest reduction potential, indicating that it is the weakest oxidizing agent.

5. **Conclusion**:
- Therefore, the weakest oxidizing agent among the given options is **chlorine gas (Cl₂)**.

### Final Answer:
The weakest oxidizing agent among the following is **chlorine gas (Cl₂)**.
