The reduction of ZnO with coke is carrie...

The reduction of ZnO with coke is carried out at a higher temperature than that of `Cu_(2)O` - explain.

Text Solution

Verified by Experts

In Ellingham diagram, `(Cu, Cu_(2)O)` line lies above `(C, CO)` line at lower temperature whereas `(C, CO)` line lies below `(Zn, ZnO)` line at higher temperature (above 1180 K). Thus reduction of ZnO in presence of coke takes place at higher temperature.
