Here’s a explanation:
What Inhibitors Do
- Inhibitors slow down a catalyst.
- They may block some active sites or change the catalyst slightly.
- The reaction still happens, but more slowly.
Difference from Poisons
- Inhibitor: slows reaction, usually reversible.
- Poison: stops reaction, often permanent.
Example
- Lead (Pb) can slow down platinum catalysts in car catalytic converters.
In short:
Inhibitors make a catalyst work slower without completely stopping it.
