1.	Which of the following is not correct observation on Ellingham diagram ?
Answer» A metal can reduce the oxide of other metal which LIES above it in ELLINGHAM diagram . CO is more effective than C as a reducing agent below `710^(@)C` `DeltaG^(@)` of metal OXIDES is higher than that of `CO_(2)` hence oxidation of metal suphides to oxides is not favourable. Need for conversion of metal sulphide to metal oxide before reduction can be explained thermodynamically. Solution :`DeltaG^(@)` of metal oxides is LOWER than of`CO_(2)` hence oxidation of metal suphide to metal oxide is favourable.
