  • The temperature of car exhaust has been measured to be 500°C. What is the value of KPat this temperature?
  • The Southern California Air Quality Management District (SCAQMD) is considering requiring car manufacturers to have engines run at lower temperatures to reduce the amount of NO formed. If they require car exhaust not exceed 400°C, how much difference (what fraction) will this make in the amount of NO in the exhaust? Do you recommend that the SCAQMD pursue this recommendation? Why or why not?
  • At what temperature does the value of DrxnG change sign?
