1.	Accordingto Ellingham diagram,theoxidationreactionofcarbontocarbonmonoxidemaybe used toreducewhichone ofthefollowingoxides atthelowesttermperature ?
Answer» ` Al_ 2O _ 3` ` Cu_ 2 O` `MGO ` `ZNO ` Solution :The GRAPHOF` Delta _f G^(@) ` vsT intheEllinghamdiagramshows that` Cu-Cu_2 O`lineis atmostat the top (i.e.,muchhigherthanthose of` AL - Al_ 2 O_ 3 ,Mg- Mg O , Zn - ZnOand Fe- FeO`lines ).Therefore, ` Cu_ 2 O` canbereducedto Cuatthelowest temperature.
