For the reaction, 2Fe2O (s) +3C (graphite) →4Fe(s)+3CO2( g) a. Calculate ΔH∗ and ΔSa using data from the back of your textbook- b. Calculate ΔG∘ at 298 K and 1000 K. c. What does the algebraie sign on ΔH∗ and ΔS∘ at each temperature say about the spontaneity of the reaction? What causes the change? d. At what temperature would the ΔGe become zero? This temperature is called the crossover temperature, explain why. c. Explain what the algebraic sign on the terms ΔH∘ and ΔS∘ says about the tendency of the reaction to go to the right or to the left as influenced by that term. f. What is the value for Keq at 298 K for the reaction?
g. At T=800 K, what would the value of ΔG be if the Pof2CO2=0.1 atm ? If the P of CO2=10 atm? (Note that Q=P3 of CO2). For this question, use the equation: ΔG=ΔH∘−TΔS∘+RT In Q, where R=8.31 J2⋅mol−1⋅K−1
