Question:

 which option the order of reducing

power is correct.

EᶱCr2O72-/Cr3+ = 1.33V

EᶱMnO4/Mn2+ = 1.51V

EᶱCl2/Cl = 1.36V

EᶱCr3+/Cr = -0.74V

(i) Cr3+ < Cl–< Mn2+ < Cr

(ii) Mn2+ < Cl–< Cr3+ < Cr

(iii) Cr3+ < Cl–< Cr2O72– < MnO4–\

(iv) Mn2+ < Cr3+ < Cl–< Cr

Solution:

Option (ii) is the answer.
