Science

Which consequence results when a catalyst degrades on a solid support, reducing surface reaction sites?

A)Observed rate constant decreases.
B)Activation energy remains unchanged.
C)Equilibrium constant changes significantly.
D)Gas diffusion to surface speeds up.

💡 Explanation

The observed rate constant decreases because fewer active sites are physically available for the catalyzed reaction according to the Arrhenius equation involving the rate constant; therefore, the reaction slows, rather than alters equilibria or activation energy.
