← ScienceWhich outcome occurs when a methane oxidation catalyst degrades due to increased pore diffusion limitations?
A)Increased reaction activation energy observed✓
B)Flame speed temporarily increases locally
C)Methane partial pressure rapidly declines
D)Equilibrium shifts towards carbon monoxide
💡 Explanation
Increased pore diffusion limitation hinders reactant access, which effectively raises the observed activation energy in the Arrhenius rate equation, because the reaction now requires molecules to overcome greater diffusional resistance. Therefore, the apparent activation energy increases, rather than equilibrium shifting; this requires prolonged carbon deposition.
