Question

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`
In which option the order of reducing power is correct?
A. `Cr^(3+) lt Cl^(-) ltMn^(2+) ltCr`
B. `Mn^(2+) lt Cl^(-) lt Cr^(3+) lt Cr`
C. `Cr^(3+) lt Cl^(-) lt Cr_(2)O_(7)^(2-) lt MnO_(4)^(-)`
D. `Mn^(2+) lt Cr^(3+) lt Cl^(-) lt Cr`

Answer 1

Correct Answer - B
(b) It is the correct order of increasing reducing strength.
