ā ScienceWhich outcome reduces NO production in internal combustion at elevated temperature?
A)High Nā-Oā activation energy barrierā
B)Increased Oā residence within cylinder
C)Decreased radical chain propagation rates
D)Elevated heat increases completion rate
š” Explanation
High activation energy implies NO formation is kinetically limited regardless of temperature; it proceeds slowly because transition state energies are significant relative to the thermal energy, therefore, minimal NO forms, rather than thermodynamic equilibrium favoring NO at such temperatures.
