In the metallurgy of antimony, the pure metal is recovered via different reactions
Chapter 17, Problem 17.5(choose chapter or problem)
In the metallurgy of antimony, the pure metal is recovered via different reactions, depending on the composition of the ore. For example, iron is used to reduce antimony in sulfide ores: Sb2S3 1s2 1 3Fe1s2 h 2Sb1s2 1 3FeS1s2 DH 5 2125 kJ Carbon is used as the reducing agent for oxide ores: Sb4O6 1s2 1 6C1s2 h 4Sb1s2 1 6CO1g2 DH 5 778 kJ Calculate DSsurr for each of these reactions at 258C and 1 atm.
