Which outcome primarily results when a heterogeneous catalyst deactivates?

💡 Explanation

Deactivation poisons catalyst active sites, therefore reducing reaction throughput because access is now limited by this blocking mechanism, rather than changes to equilibrium or surface area that usually enhance rate.
