Out of coke and CO, which is better reducing agent for the reduction of ZnO? Why? |
| Answer» Solution :COKE (C ) is a better REDUCING AGENT for the reduction of ZnO.Because,when we use coke,the reduction can be easily out at 673 K.Thus carbon (Coke) reduce zinc OXIDE more esily than carbon monoxide (CO).From the Ellingham diagrams ,it is quite clear that the reduction of zinc oxide is more favourble USING coke (`DeltaG` for the formation of carbon monoxide from is more negative). | |
