← ScienceWhich risk increases within a catalytic converter due to incomplete reagent mixing?
A)Runaway reaction rate acceleration✓
B)Depletion of the precious metals
C)Equilibrium shift favoring reactants
D)Decreased activation energy required
💡 Explanation
A runaway reaction rate increases when incomplete mixing creates localized high concentrations of reactants. This triggers thermal runaway because the exothermic reaction rate accelerates exponentially, rather than remaining stable. Therefore, the reaction may run uncontrolled
