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)

Why a catalyst is not involved chemically in chemical reaction?

The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.


What effect does catalyst on a reaction?

A catalyst speeds up the rate of a reaction.


Is a catalyst used up in a reaction?

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.


What is the opposite reaction of a Catalyst?

The opposite of a catalyst is an inhibitor, something that suppresses or slows a reaction.


What effect does a catalyst having a reaction?

A catalyst speeds up the rate of a reaction.


will a catalyst change the enthalpy of a reaction in a chemical reaction?

No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!


What substance increases the rate of a reaction but is not itself changed by the 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).


Which component is affected when a catalyst is added to a chemical reaction?

The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.


What is a substance that speeds up a reaction?

A catalyst is a substance that speeds up the rate of a chemical reaction.


Where is a catalyst written in an equation?

A catalyst is typically written above the arrow in a chemical equation, indicating its role in speeding up the reaction without being consumed itself. It is not listed as a reactant or product in the equation.


Is the catalyst consumed in the reaction process?

In a chemical reaction, a catalyst is not consumed and remains unchanged at the end of the reaction process.


What catalyst is used to speed up a reaction?

A catalyst is a substance that initiates or accelerates a reaction. The catalyst will vary depending on the reaction so it is not possible to give a definitive answer to the question.
