Problem 2 (30 pts) Problem 2. Case Problem Analysis The general process of iron smelting is observed in Figure 2 in Problem 1, where the iron ore and other burden materials are reduced by carbon monoxide as a by-product of coke combustion. The reduction of the metallic components results in a release of carbon dioxide and excess carbon monoxide. With increasing awareness and action to the association of carbon emissions and climate change, there are different technologies being employed to minimize the effect of these green house gases. One specific alternative to carbon reduction is H2 gas reduction, albeit the existing challenges. Explain using your knowledge from thermodynamics and kinetics why carbon is an effective reductant to iron (Clue: you can use equilibrium diagrams and rate constants etc. for your explanation). What is the basis of using hydrogen gas as an alternative? Are there other alternatives that can be used to reduce iron ore into molten iron? Justify why these alternatives work based on your prior metallurgical knowledge. Research atleast 2 additional working methods aside from alternative reductants that can reduce carbon emissions. Why is this important for you as a metallurgical engineer
