Verified by Experts

Metallurgical reductions are usually high temperature processes. At elivated temperatures, hydrogen may form hydrides with metals. Metallurgical operations in open vessels lead to be combination of hydrogen with oxygen leading to the formation of water.
Ellingham curve has a positive slope and is parallel to the curves of several metal oxides.
