Which of the following statements, about the advantage of roasting of sulphide ore before reduction, is not trué? roasting of the sulphide to the oxide is thermodynamically feasible, carbon and hydrogen are suitable reducing agents for metal sulphides, The Delta_f G^o of the sulphide is greater than thóse for CS_2 and H_2 S , The Delta_f G^o is negative for roasting of sulphide ore to oxide.

In an experiment pure carbon monoxide was passed over red hot copper oxide. CO_(2) , so produced, weighed 0.88 g and the weight of copper oxide was reduced by 0.3232 g. Calculate the atomic weight of carbon.

Assertion: Carbon is a good reducing agent for oxides, while poor reducing agent for sulphide. Reason: The slope of Delta_(f) G^(@) Vs T line of CO_2 is positive and of CS_2 is negative.
