Extraction of metals like Ag and Hg from their oxides take place high temperature.

Text Solution

Verified by Experts

For `Ag_(2)O` and `HgO, Delta_(f)G^(@)` becomes positive at higher temperature.
This suggests that these oxides are unstable at high temperature and hence decompose to liberate the corresponding metal.
