The blast furnace is a process whose main purpose is to obtain metallic iron $($Fe$)$ from Fe$2$O$3$ ore and coke coal $($C$),$ where the main reaction is: Fe$2$O$3+3$C $=2$Fe $+3$CO Although other side reactions occur simultaneously, among them is: Fe$2$O$3+$ C $=2$FeO $+$ CO Solve the following problem considering both reactions. A blast furnace is fed with $600$ pounds of coking coal $($C$)$ and one ton $(200$ lb$)$ of pure iron oxide $($Fe$2$O$3),$ producing $200$ pounds of pure iron $($Fe$),183$ pounds of Fe$2$O$3.$ Calculate the following: A$)$ Draw flowchart. B$)$ Percentage of excess carbon supplied based on the main reaction. C$)$ The percentage conversion of Fe$2$O$3$ to Fe$.$ D$)$ The pounds of coal consumed and pounds of CO produced per ton of Fe$2$O$3$ loaded. E$)$ Selectivity of the process $($Fe over FeO$).$
