🌟 Key Idea: Catalysts speed up reactions without being used up themselves!

What is a catalyst?

  • Definition: A substance that boosts the speed of a chemical reaction but isn't changed by it.
  • Cool Fact: Since they don’t get used up, even a tiny bit can catalyse a reaction many times! It's like having a reusable rocket booster. 🚀

Platinum – not just bling

  • Platinum isn’t only a shiny metal for jewelry. It's also an inorganic catalyst.
  • Real-world Application: 🚗 Catalytic converters in cars have platinum. They turn harmful unburned hydrocarbons from exhaust into friendly carbon dioxide and water. So, your car doesn’t just run; it cleans up after itself!
