3.14 How much electricity is required in coulomb for the oxidation of

(i) 1 mol of H2O to O2?

(ii) 1 mol of FeO to Fe2O3?

Hint: Use Faraday’s Laws of Electrolysis
(i) According to the question,
H2OH2+12O2
Now, we can write:
O2-12O2+2e-
Electricity required for the oxidation of 1 mol of H2O to O2=2 F
= 2 x 96487 C
= 192974 C
 
(ii) According to the question,
Fe2+Fe3++e-1
Electricity required for the oxidation of 1 mol of FeO to Fe2O3= 1 F
=96487 C
