Which outcome occurs when a packed-bed reactor experiences significant catalyst fouling?

💡 Explanation

Significant fouling increases flow resistance and reduces active sites, so the reaction rate declines because diffusion limitations dominate inhibiting reactants from reaching catalysts, therefore pressure drop increases and rate reduces rather than heat transfer improvement or lowering activation energy.
