Vedclass · Answer

(C) The extraction of iron from $Fe_2O_3$ is carried out in a blast furnace by heating with coke $(C)$.The coke reacts with oxygen to form $CO$,which acts as the reducing agent:$Fe_2O_3   3CO 	o 2Fe   3CO_2$Thus,the assertion is correct.The reaction $Fe_2O_{3(s)} 	o 2Fe_{(s)}   3/2 O_{2(g)}$ is not spontaneous because it involves the breaking of strong metal-oxygen bonds,which is highly endothermic $(\Delta H > 0)$ and results in an increase in entropy $(\Delta S > 0)$,but at standard temperatures,the Gibbs free energy change $(\Delta G = \Delta H - T\Delta S)$ remains positive.Therefore,the reason is incorrect.

Assertion : Extraction of iron metal from iron oxide ore is carried out by heating with coke.
Reason : The reaction,
$Fe_2O_{3(s)} \to Fe_{(s)} + 3/2 O_{2(g)}$ is a spontaneous process.
