Between C and CO, which is a better reducing agent for ZnO? |
|
Answer» Case – I : [Coke as reducing agent] ZnO + C → Zn + CO, ∆G° becomes lesser as the T is more then 1120K. Case – II : [CO as reducing agent] ZnO + CO2 → Zn + CO, ∆G° becomes lesser when the T is more then 1323K. → The value of ∆G° is negative for a reaction to occur. → In the equation (1) ∆G° becomes negative at low temperature- so equation (1) is feasible i.r. C is a better reducing agent for ZnO. |
