What organic molecule acts as a catalyst for chemical reactions?
It either lowers the activation energy or increases the activation energy, allowing the reaction to occur faster or slower respectively. It modifies the rate of the reacti…on.
A catalyst speeds up the rate of a chemical reaction.
They speed them up
A catalyst speeds up chemical reactions without suffering chemical change itself. It basically increases the amount of collisions made in a reaction, therefore speeding it up …(as collisions and their force depict the speed of the reaction), however, it is not used up in the reaction, making it reusable, especially in industrial processes
Proteins can perform many different functions in living cells One major function acting as a catalyst for chemical reactions can also be performed by what other kind of organic molecule?
A catalyst accelerates the process of a chemical reaction. If a reaction is a slow one then by introducing a catalyst would speeden up the process. For example :- The reaction… between hydrogen and nitrogen to create ammonia is a slow reaction. Finely divided iron act as a catalyst.
Is a enzyme a protein that acts as a catalyst in a chemical reaction that takes place in a living thing?
A chemical catalyst is a substance that lowers the required activation energy of a reaction. The activation energy is the amount of energy required to "activate" or start a pr…ocess, this can be in the form of many things, such as heat. A chemical catalyst can be seen as a kind of shortcut in a chemical process to speed things up. A catalyst can also be used to increase the activation energy, so that the reaction will slow down. This is useful for slowing down reactions that are normally too fast to witness.
These protein species are known as Enzymes.
Yes, a catalyst can be re-used, because It is NOT actually used in a chemical reaction. A catalyst will increase the rate of reaction by attracting reactants, but the cata…lyst is not a reactant. However, the reuse cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalys.
You could re-do the experiment without the substance and if the reaction completed slower then the substance acted as a catalyst. Also catalysts dont get used up themselves so… if the substance did get used up in the reaction (there was more / less of it at the end of the reaction) then it probably didnt act as a catalyst. Hope this helped :)
Catalysts are used in Chemical Reactions to speed up a reaction& convert more of the reactants into products.
The platinum catalyst in a car's catalytic converter works through adsorption to change toxic carbon monoxide into less-toxic carbon dioxide. A catalyst that inv…olves an intermediate compound is chlorine. In the ozone layer of our Earth's atmosphere there are many ozone molecules, composed of three atoms of oxygen. If a chlorine atom is present, it will act as an intermediate compound and steal one oxygen atom from ozone, leaving stable oxygen. The chlorine-oxygen compound formed is unstable, and will break down to release its oxygen, letting the chlorine atom repeat the process about a million times a second.
