In the extraction of copper from its sulphide ore, when ore is subjected to roasting, some of it is oxidised to Cu 2 O which reacts with the remaining Cu 2 S (sulphide ore) to give copper metal. Cu 2 S +2Cu 2 O → 6Cu +SO 2 ↑ In this process, Cu 2 S behaves as reducing agent.

The Gibbs free energy of formation (Δ f G) of Cu 2 S is less than that of H 2 S and CS, H 2 and C cannot reduce Cu 2 S to Cu.. On the other hand, the Gibbs free energy of formation of Cu 2 O is greater than that of CO. Hence, C can reduce Cu 2 O to Cu.. C (s) +Cu 2 O (s) → 2Cu (s) + CO (g). Hence, the extraction of copper from its pyrite ore is difficult than from its oxide ore ...

So, um, the problem, the conversion of a copper or two copper. Ah. And so we want to know what the, uh, delta G value is for coupling this reaction with the sulphur conversion to sulfur dioxide. Um, and so we first need to get the, uh, Delta G zero for the given reaction. The, uh, reaction here. And so that's products two times the delta G zero for the copper minus the delta G zero.
