Greetings, ME major here trying to brush the cobwebs off my chemistry. I can't seem to remember or recognize anything on my old chemistry textbooks regarding the optimization of a reaction. I question whether it was even taught. I'm trying to determine the most favorable conditions to ensure minimal limiting reagent and maximum Fe and H2O yield for the reduction of ferrous-oxide (wustite) with hydrogen gas. FeO + H2 --> Fe+2 + H2O It is my understanding that the catalyst for this reaction is heat. One source claims that it takes place at temperatures near 350oC [https://chemiday.com/en/reaction/3-1-0-5399]. However, this is just one source and I'm not sure how reliable the claim may be. I want to know how to determine the temperature required to completely react 1 mole of wustite with 1 mole of hydrogen gas at the highest reaction rate for a given pressure. I've been looking for research done on this matter, which studies the reaction in a range of temperatures, such as Further Insight into the Reaction FeO+ + H2 → Fe+ + H2O: Temperature Dependent Kinetics, Isotope Effects, and Statistical Modeling [https://pubs.acs.org/doi/10.1021/jp5055815] and Reactions of Fe with H2O and FeO with H2. A Combined Matrix Isolation FTIR and Theoretical Study [https://pubs.acs.org/doi/pdf/10.1021/jp010914n]. I find them very heavy on jargon and I've never seen the addition of variables like D to a reaction, such as FeO+ + D2 → Fe+ + D2O If anyone could lead me in the right direction, that would be much appreciated.
