← ScienceWhich consequence emerges when a zeolite catalyst degrades, thus decreasing its effective rate constant?
A)Lowered apparent activation energy occurs
B)Reaction reaches pseudo-equilibrium sooner✓
C)Decreased reactant diffusion is observed
D)Substrate adsorption sites permanently increase
💡 Explanation
Reduced effective rate constant causes the reaction to appear to reach equilibrium sooner because the rate-determining steps are slowed, therefore the reaction stabilizes seemingly earlier rather than achieving true chemical equilibrium with all products formed.
