Question
The standard reduction potential data at 25oC is given below
Eo (Fe3+, Fe2+) = + 0.77 V ;
Eo (Fe2+, Fe) = - 0.44 V ;
Eo (Cu2+, Cu) = + 0.34 V ;
Eo (Cu+, Cu) = + 0.52 V ;
Eo (O2(g) + 4H+ + 4e- → 2H2O] = +1.23 V ;
Eo [(O2(g) + 2H2O + 4e- → 4OH- )] = +0.40 V ;
Eo (Cr3+, Cr) = -0.74 V ;
Eo (Cr2+, Cr) = -0.91 V ;
Match Eo 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 :
