Want this question answered?
In any reaction, a catalyst is never used up or changed. This means that at the end of every reaction you should always get your catalyst back. sometimes in the course of the reaction, the catalyst is used up, but by the end of the reaction it will always be reformed completely.
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 catalyst 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.
A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction. basically it increases or decreases the speed of a chemical or biological reaction, but it does not get itself involved in the reaction. hoped this helped (:
A Catalyst
In chemistry, they can work by adsorption (although there are other methods). This is when the catalyst attaches itself to the reactant particles and then weakens the bond between them, making it easier to react, thus 'lowering the activation energy' (the energy required for a reaction to start).
All the catalyst remains as it is not incorporated into the reaction products, it just speeds up the reaction time.
- it speeds up the reaction by offering an alternative root. - it remains the same at the end of the reaction.

A catalyst must change the rate of a chemical reaction. It must be unchanged at the end of the reaction.
Adding a catalyst will make the reaction happen faster because the catalyst makes the Activation Energy (the energy required for the reaction to take place) to lower. Meaning more molecules can acquire this lower number of energy. A chemical reaction that involves a catalyst is a special type. A catalyst, in a given chemical reaction, is something that is both an input *and* an output of the reaction equation. What that means, practically, is that a small amount of catalyst is enough to process any amount of the other inputs. (More catalyst means that a given amount will be processed faster.)

Yes a catalyst can be reused because it unchanged chemically or in mass at the end of a reaction. However, this cannot be done indefinitely then, depending on the severity of the reaction conditions, it can be occur a small, but accumulative deactivation of the catalyst

No; a catalyst is used to speed up a reaction, and catalysts should remain in their initial states at the end of a reaction. Catalysts include: Fe Ni H2SO4 H3PO4 ** a system may act as a catalyst for altering water by definition the G7 water catalyst is such.
Provided the catalyst is appropriate for the reaction, it will accelerate the reaction. In other words, the reaction will reach equilibrium between reactants and products faster than it would otherwise have done. The catalyst is unchanged, i.e. at the end of the reaction it is in the same chemical state that it was in at the start. In living systems, the catalysts are made by cells and are called enzymes.
