Ag2(g)O and HgO are unstable at moderate temperature and they will decompose on heating even in the absence of a reducing agent. Why?

Answer»

Ellingham diagram for the formation of Ag2(g)O and HgO is at upper part of the diagram and their decomposition temperatures are 600 and 700 K respectively. It indicates that these oxides are unstable at moderate temperatures and will decompose on heating even in the absence of a reducing agent.
