Question:medium

In a combustion process, the "Theoretical Adiabatic Flame Temperature" is the maximum temperature the products can reach. This temperature is lower in practice because

Show Hint

At high temperatures, dissociation acts as a natural chemical buffer.
The heat absorbed by endothermic dissociation limits the maximum temperature in gas turbines, rockets, and internal combustion engines, keeping it below theoretical values.

  • real reactions are always endothermic
  • part of the energy is consumed by the dissociation of product molecules
  • the heat capacity of the products decreases at high temperatures
  • the nitrogen in the air acts as a catalyst, absorbing energy
