Answer» Question 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. Answer:(i)We have 1 mol of H2O1 mol of H2O will give one atom of OCharge on O = – 2Electricity required =n F= 2 × 96487 Coulombs= 192974 Coulombs= 1.93 × 105Coulombs (ii)Charge on Fe in compound FeO = + 2Charge on Fe in compound Fe2O3= + 3Change in charge n = 1Electricity required = nF= 96487 Coulombs= 9.65 × 104Coulombs 1.93×105 coulombs is right answer 2 Faraday required for first case and 1F required for 2nd case.. options (ii) is the correct answer. How Much Electricity Is Required In Coulomb For The OxidationOf (i) 1 Mol Of H2O To O2. How Much Electricity Is Required In Coulomb For The OxidationOf (i) 1 Mol Of H2O To O2. |
