a3 [ /23 pts): In the iron manufacturing industry, the efficient conversion of iron oxide (Fe20;) into pure ironis crucial. The primary reaction that occurs in a blast furmace is: Fe,0, + 3C 2Fe + 3C0 However, there are side reactions that can hinder efficiency, such as: Fe,0, + C + 2Fe0 + CO In a typical scenario, 600 pounds of carbon are mixed with 1 ton (2000 pounds) of pure iron oxide. This process yields 1200 pounds of pure iran, 183 pounds of iron(II) oxide (FeO), and 85 pounds of unreacted iron oxide (Fe0s). 600 Ibm of carbon are combined with 1 ton of pure iron oxide (Fe,03). This combination yields 1200 pounds of pure iron, along with 183 pounds of iron(II) oxide (FeO) and 85 ibm of unreacted iron oxide (Fez03). Use extent of reaction method wherever possible to : a) Calculate the percentage of excess carbon used based on the desired reaction. The percentage of excess air used [ /7] b) Determine the total % conversion of iron oxide (FeO ) then the % conversion of Fe203 into pure iron (Fe). [ /5) c) Compute the total pounds of carbon consumed and the pounds of carbon monoxide (CO) produced for every ton of iron oxide processed. [ /9] d) Evaluate the selectivity of pure iron relative to iron(ll) oxide (FeO). [ {2]
