Which outcome occurs when a catalyst degrades during continuous chemical processing?

A)Reaction rate gradually decreases.
B)Equilibrium shifts toward products.
C)Activation energy immediately increases
D)Reactant concentration becomes non-uniform.

💡 Explanation

Lower catalyst concentration reduces active sites, because the law of mass action posits that reduced surface areas decrease the **reaction rate**. Therefore, process output declines rather than promoting equilibria shift or increased activation energy, a catalyst breakdown affects reaction speed.
