โ ScienceWhich risk increases when fuel-air mixtures approach stoichiometric ratio during combustion?
A)Increased rate of quenching reactions
B)Reduced detonation propagation velocity
C)Suppressed formation of combustion radicals
D)Elevated rate of chain-branching reactionsโ
๐ก Explanation
The rate of chain-branching reactions will be elevated. This is because at stoichiometry flame temperature maximizes โ which increases the rate of the overall combustion. This leads to faster exponential growth in radical concentration, therefore increasing the explosion risk, rather than other quenching or propagation effects.
