WHAT IS CATALYST ? WHAT ITS FEATURES ? NAME SOME CATALYST WITH THEIR SEVERAL USAGES ?
Answers
Answer:
In Chemistry, catalysts are defined as those substances which alter the rate of reaction by changing the path of reaction. Most of the time a catalyst is used to speed up or increase the rate of the reaction. However, if we go into a more deeper level, catalysts are used to break or rebuild the chemical bonds between the atoms which are present in the molecules of different elements or compounds. In essence, catalysts encourage molecules to react and make the whole reaction process easier and efficient.
Some of the important characteristic features of catalysts are,
1.A catalyst does not initiate a chemical reaction.
2.A catalyst does not be consumed in the reaction.
3.Catalysts tend to react with reactants to form intermediates and at the same time facilitate the production of the final reaction product. After the whole process, a catalyst can regenerate.
Answer:
A catalyst is a substance that speeds up a chemical reaction, but is not consumed by the reaction; hence a catalyst can be recovered chemically unchanged at the end of the reaction it has been used to speed up, or catalyze.
These are some features of catalyst :-
The catalyst remains unchanged (in mass and chemical composition ) in the reaction (Activity of catalyst.)
A small quantity of the catalyst is required.
The catalyst does not change the equilibrium constant.
The catalyst can not make impossible reaction to occur and does not intiate a reaction.
These are uses of catalyst :-
Catalysts speed up a chemical reaction by lowering the amount of energy you need to get one going. Catalysis is the backbone of many industrial processes, which use chemical reactions to turn raw materials into useful products. Catalysts are integral in making plastics and many other manufactured items.
