- The useful idea
Catalysis (, kə-TAL-iss-iss) is the increase in rate of a chemical reaction due to an added substance known as a catalyst ( KAT-əl-ist).
- How it works
Catalysts are not consumed by the reaction and remain unchanged after the reaction.
- Why it matters
If the reaction is rapid and the catalyst is recycled quickly, a very small amount of catalyst often suffices; mixing, surface area, and temperature are important factors in reaction rate.
Why this matters
Look for Catalysis the next time you notice this pattern in everyday life.
