SUMMARY

The discussion centers on the conversion of carbon monoxide (CO) to carbon dioxide (CO2) in high-temperature environments, such as internal combustion engines. It is established that the reaction 2CO (g) + O2(g) → 2CO2 (g) is spontaneous, but the conversion does not occur completely due to the limited time available for the reaction to proceed. The Gibbs free energy calculations indicate that while both the forward and reverse reactions are thermodynamically spontaneous, the reverse reactions are endothermic and less favorable under these conditions.

PREREQUISITES
  • Understanding of exothermic and endothermic reactions
  • Familiarity with Gibbs free energy concepts
  • Knowledge of combustion processes in internal combustion engines
  • Basic thermodynamics principles
NEXT STEPS
  • Calculate Gibbs free energy changes for combustion reactions
  • Research the kinetics of CO to CO2 conversion in high-temperature environments
  • Study the thermodynamics of combustion reactions in internal combustion engines
  • Explore the impact of temperature on reaction rates and equilibrium
USEFUL FOR

Chemistry students, mechanical engineers, and professionals involved in combustion research or internal combustion engine design will benefit from this discussion.

im wondering what reaction would likely occur
2NO (g) → N2(g) + O2(g) or the reverse

2CO (g) + O2(g) → 2CO2 (g) or the reverse

well the first one would occur if it were the reverse because of the high temperatures in the engine, but I am wondering about carbon monoxide, what do you guys think
 
Physics news on Phys.org
wait a minute, All internal combustion engines depend on the exothermic chemical process of combustion
so therefore these are more likely to occur the way i wrote them
 
Calculate the change in the gibbs free energy for each reaction and the reverse from the thermodynamic data in the back of any general chemistry text. That will tell you which is going to more spontaneously occur.
 
i did, and the ones i wrote are both spontaneous, but the reverse are endothermic
 
Thermaldynamically, those reaction are spontaneous, but the time is so short that they can not convert completely. Reactions take time.
