- Catalysts
- Industrial processes
- They can be uses for hydrogenation/ hardening fats
- Cracking
- Catalytic converter in cars
- Haber process (ammonia)
- Benefits for chemical industry
- Catalysts are used whenever possible in industr to increase the rate of reaction and reduce energy costs
- They can be used in medicine without havin metal in the catalysts which makes them cheaper.
- Disadvantages
- Very expensive to buy and if making more than one product you need to buy more than one catalyst as they don't all use the same catalyst.
- They can be 'poisoned' by impurities so they stop working meaning you have to keep your reaction mixure very clean.
- Exothermic
- They give out energy to the surrounding
- Chemicals lose energy
- Temperature goes up
- Enodothermic
- Takes in energy from the surroundings
- Temperature goes down
- Chemicals gain energy
- Industrial processes
