4.6+Catalysts+in+action

Catalysts are used in many places including cars, the smoke from the engine passes over a catalytic converter which removes the oxygen from the nitrogen oxides and reacts with the carbon monoxide (a deadly gas) and results in Carbon dioxide.

Catalysts are used in washing powders as well, not just any catalysts though, Biological catalysts!!!!!!! Which are also known as enzymes which break down dirt particles in the clothes and make then white or whatever colour they were naturally. Thats all there is thats worth knowing on this section.
