According to the given diagram Al can reduce ZnO. 3ZnO + 2Al arrow 3Zn + Al2O3

Q. The correct statement regarding the given Ellingham diagram is:

At $800^{\circ} C$ , $C u$ can be used for the extraction of $Z n$ from $Z n O$

At $500^{\circ} C$ coke can be used for the extraction of $Z n$ from $Z n O$

Coke cannot be used for the extraction of $C u$ from $C a_{2} O$ .

At $1400^{\circ} C$ $A l$ can be used for the extraction of $Z n$ from $Z n O$

According to the given diagram Al can reduce ZnO.
$3 Z n O + 2 A l \to 3 Z n + A l_{2} O_{3}$
