The oxidation of acid by manganate ions
In autocatalysis, the reaction is catalyzed by one in every of its products. The reaction tends to be quite slow at temperature. It is used as a titration to seek out the concentration of potassium manganate solution, and is often disbursed at a temperature of approximately 60°C.
The reaction of this is catalyzed by manganese ions. Before the reactions start there are none, and then begins at an extremely slow pace. However, if you take a look at the equation, you’ll find manganese ions amongst the different types of products. More and more catalysts are produced because the reaction proceeds so the reaction races.
Homogeneous catalysis
This has the catalyst within a similar phase due to the reactants. Typically, everything is present as a gas or contained in a single liquid phase.
Catalytic converters
Catalytic converters transform poisonous molecules such as monoxide into more harmless molecules such as carbonic acid gas or nitrogen. They tend to use more expensive metals such as platinum, palladium and rhodium.
It is important to note that the metals used are deposited as thin layers onto what is considered that of a ceramic honeycomb. This increases expansion and keeps the quantity of metal kept to a minimum.
