In any chemical reaction, generally only reactants and products are listed. A catalyst is something that is used during a chemical reaction to change the rate of reaction but does not chemically interact with any of the reactants . It does not change any chemical propertied, it just speeds up the reaction. Since it's not reactant or product, it's not usually listed in a reaction.
Catalysts may be indicated in the reaction by beings shown as a superscript over the arrow. This example shows platinum as a catalyst H2C=CH2(g) + H2(g) ----- Pt----> H3CH-CH3(g)
When reactants are binding to the surface of the catalyst, it is important that the catalyst is strong enough to allow a reaction to take place, however having a strong catalyst could mean that the products could permenantly bind to the catalyst, which is a problem. So if the catalyst is too strong, the catalyst isnt very sucessful, and if it is too weak, it also isn't sucesful.
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.
With a catalyst the reaction rate is higher.
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.
A catalyst speeds up the rate of a reaction.

A catalyst is a substance that speeds up the rate of a chemical reaction.
It's called a catalyst. A catalyst is present during a chemical reaction but does not participate as a reactant or product. A catalyst lowers the reaction's activation energy, making the reaction easier to happen. In the equation for a chemical reaction, the catalyst's formula appears in small notation above the "yield" arrow (format won't let me show you an example.) An example of a catalyst is potassium iodide (KI) speeding up the decomposition of hydrogen peroxide (H2O2).

Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
None: The catalyst remains unchanged, but the catalyst also speeds up the reaction.
