Real-World Examples of Catalysts

1. Catalytic Converters

   • You can find these in cars.
   • They use materials like platinum and palladium to change harmful gases into safer ones.
   • Because of this, they can cut down pollution by about 90%.

2. Enzymes in Our Bodies

   • Enzymes are natural helpers that make reactions in our bodies happen faster.
   • For example, the enzyme called amylase helps break down starch much quicker—about a million times faster!

3. Haber Process

   • This is a way to make ammonia, and it uses iron as a catalyst.
   • This process can create about 15% of ammonia in one go.
   • It’s really important for making fertilizers, which helps grow food all over the world.
