Vedclass · Answer

(A) In a blast furnace,the decomposition of limestone $(CaCO_3)$ into calcium oxide $(CaO)$ and carbon dioxide $(CO_2)$ is an endothermic reaction.This reaction requires heat to proceed: $CaCO_3(s) \xrightarrow{\Delta} CaO(s) + CO_2(g)$.The other reactions listed,such as the combustion of carbon $(C + O_2 \rightarrow CO_2)$ and the reduction of iron ore $(Fe_2O_3 + 3CO \rightarrow 2Fe + 3CO_2)$,are exothermic.

Which of the following reactions occurring in a blast furnace is endothermic?
