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).

∙ 9y agoThis is called a catalyst. A catalyst lowers, or can raise, the activation energy. This change can make the reaction occur faster, but the catalyst is not consumed in the reaction.

What is a substance that speeds up a chemical reaction without permanently being changed itself?
A catalyst.
A substance that speeds up a chemical reaction without undergoing a permanent change itself is?
A substance that speeds up a chemical reaction without undergoing a permanent change itself is a catalyst.
What are products reactants and catalysts?
* Reactants: the initial compounds in a chemical reaction. * Products: the final compounds in a chemical reaction. * Catalyst: a chemical compound which help the chemical reaction but not react with the other compounds.
What is a A substance that speeds up a chemical reaction without being permanently changed itself?
This is a catalyst. A catalyst doesn't get destroyed during the reaction. Rather it's more of a reaction site where two substances can combine. One example of a catalyst is amyl alcohol, which can be used to produce pure potassium metal. However, it's destroyed during the process if there are impurities in the reaction because it's consumed in other reactions. Other examples of catalysts include catalase, platinum, and manganese(IV) oxide.
What is a Catalyst mean in chemistry?
In Biology, a catalyst is a substance which speeds up a chemical reaction, without being changed themselves. Biological catalysts are found in living organisms.
What are catylistas?
Do you mean Catalysts? If you do, then its any substance that increases the rate of a reaction without itself being consumed.
What is a substance that speeds up a chemical reaction without permanently being changed itself?
A catalyst.
The role of a catalyst?
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 (:
What is a catylast?
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. a person or thing that precipitates an event.
What is a substance which helps make a chemical change happen but is not changed itself in the process is called?
Catalyst: a substance which speeds up a chemical change or enables the change to take place at a lower tempature, and is not changed or used up in the reaction.
Do barium and barium have a reaction?
No. A substance will not react with itself.
Do enzymes speed up a chemical reactions?
Ensymes speed up a chemical reaction by acting as organic catalyst, a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
A substance that speeds up a chemical reaction without undergoing a permanent change itself is?
A substance that speeds up a chemical reaction without undergoing a permanent change itself is a catalyst.
Why a substance that speeds up a chemical reaction without being permanently changed itself?
A Catalyst.From wikipedia: "Catalysis is the process in which the rate of a chemical reaction is increased by means of a chemical substance known as a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. The catalyst may participate in multiple chemical transformations."http://en.wikipedia.org/wiki/Catalyst
A is a substance that can make something happen faster but is not changed itself?
the answer is a catalyst
What is a substance that brings about reactions without being changed itself?
A catalyst
What is a catalyst?
A catalyst is a substance that speeds up a given chemical reaction by lowering its activation energy without itself being used up.
