Using the data given below:
`E_(Cr_(2)O_(7)^(2-)|Cr^(3+))^(@)=1.33V E_(Cl_(2)|Cl^(-))^(@)=1.36V`
`E_(MnO_(4)^(-)|Mn^(2+))^(@)=1.51V E_(Cr^(3+)|Cr)=-0.74V`
Find the most stable oxidised species.

Options

A. `Cr^(3+)`
B. `MnO_(4)^(-)`
C. `Cr_(2)O_(7)^(2-)`
D. `Mn^(2+)`

Explanation

To determine the most stable oxidized species from the given standard reduction potentials, we need to analyze the provided data step by step.

### Step 1: Understand the Given Data
We have the following standard reduction potentials:
1. \( E^\circ_{Cr_2O_7^{2-} | Cr^{3+}} = 1.33 \, V \)
2. \( E^\circ_{Cl_2 | Cl^-} = 1.36 \, V \)
3. \( E^\circ_{MnO_4^{-} | Mn^{2+}} = 1.51 \, V \)
4. \( E^\circ_{Cr^{3+} | Cr} = -0.74 \, V \)
