Which consequence results when a catalyst degrades within an oscillating chemical clock reaction?

A)Decreased oscillatory signal amplitude
B)Increased reaction equilibrium shift
C)Elevated activation energy threshold
D)Greater frequency of product formation

💡 Explanation

Catalyst degradation lowers the effective catalytic activity because it reduces the availability of active sites to lower the activation energy barrier, leading to a damping `oscillation`. Therefore, the oscillatory amplitudes decrease, rather than changes to the kinetic rate or activation energy.
