← ScienceWhich outcome occurs when an oxidation reaction reaches dynamic equilibrium in a catalytic converter?
A)Reaction rates equal forward and reverse✓
B)Catalyst deactivation from thermal stress
C)Unreacted pollutants increase linearly with flow
D)Equilibrium constant shifts to maximize reactants
💡 Explanation
When dynamic equilibrium is reached, forward and reverse oxidation reactions proceed at equal rates because the overall change in concentration of reactants and products is zero, even though individual reactions continue. Therefore A is the result, rather than catalyst deactivation, unreacted pollutants, or equilibrium constant shifts, which do not define equilibrium.
