← ScienceWhich phenomenon limits methane combustion kinetics at low temperatures?
A)Reduced concentration radical chain carriers✓
B)Increased heat loss convective cooling
C)Enhanced formation carbon monoxide byproduct
D)Decreased mixing fuel air reactants
💡 Explanation
At low temperatures, the thermal energy is insufficient to sustain radical chain propagation reactions because activation energies not exceeded, reducing radical concentrations, thereby slowing the reaction. Therefore reduced radical carriers determine the kinetics, rather than cooling, CO formation, or fuel/air mixing which have other temperature dependencies.
