Question

The standard reduction potential data at 25^oC is given below
E^o (Fe³⁺, Fe²⁺) = + 0.77 V ;
E^o (Fe²⁺, Fe) = - 0.44 V ;
E^o (Cu²⁺, Cu) = + 0.34 V ;
E^o (Cu⁺, Cu) = + 0.52 V ;
E^o (O₂(g) + 4H⁺ + 4e^- → 2H₂O] = +1.23 V ;
E^o [(O₂(g) + 2H₂O + 4e^- → 4OH^- )] = +0.40 V ;
E^o (Cr³⁺, Cr) = -0.74 V ;
E^o (Cr²⁺, Cr) = -0.91 V ;
Match E^o of the redox pair in List-I with the values given in List-II and select the correct answer using the code given below the lists :
