3. 4. 5. Predict the sign of AS rxn for the following processes. a) 2K (s) + F2(g) 2KF (s (s) b) 3 NO2(g) + H₂O 2HNO3(1) + NO(g) Also calculate the AS rxn value for part b using values from a table. How would the value of AS°rxn differ if HNO3(aq) were formed? Why? The overall process occurring in a blast furnace during the production of iron is the reaction of Fe₂O3 and carbon to produce Fe and CO₂. a) Calculate AH°rxn and AS rxn assuming carbon is graphite. b) Calculate AGº at 298K. Is the reaction spontaneous at this temperature? c) Is the reaction spontaneous at a low or a high temperature? Explain. d) At what temperature does the reaction become spontaneous? A student is upset because the instructor has marked the equation CH4(g) + H₂O(g) CH3OH(g) + H2(g) wrong on a test. If you were an instructor, how would you show the student that the reaction does not occur?
