The Standard free energy of formation of Cu2S is greater than those of CS2 & H2S .Hence , niether carbon nor hydrogen can reduce Cu2S to Cu metal. On the other hand , standard free energy of formation of Cu2O is much lower than that of CO2 & hence , carbon can easily reduce Cu2O to Cu. Cu2O+C (s) -> Cu(s) +CO(g)
