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).

What is a substance that speeds up a chemical reaction without permanently being changed itself?
A catalyst is a substance that speeds up a chemical reaction by lowering the activation energy needed for the reaction to occur, without being consumed or permanently altered in the process.
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 is the role of iodine in the reaction between peroxide and a substance?
Iodine acts as a catalyst in the reaction between peroxide and a substance, speeding up the reaction without being consumed itself.
A material that increases the rate of a reaction is called what?
A material that increases the rate of a reaction is called a catalyst. Catalysts work by lowering the activation energy required for a chemical reaction to occur, thereby increasing the reaction rate without being consumed in the reaction itself.
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 are catylistas?
Do you mean Catalysts? If you do, then its any substance that increases the rate of a reaction without itself being consumed.
How is a catalysts different from a reactant?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process, while a reactant is a substance that participates in a chemical reaction and is consumed. Essentially, a catalyst speeds up a reaction without being changed itself, while a reactant is consumed during the reaction.
What is the substance labeled catalyst also known as?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction itself. It provides an alternative pathway for the reaction to occur more quickly by lowering the activation energy barrier.
What is substance itself is acting as a -----agent?
Substance itself acting as a "----agent" refers to a material or chemical that facilitates a specific reaction or process. For example, in a chemical reaction, a catalyst is a substance that increases the reaction rate without being consumed. In pharmacology, a drug can serve as an active agent that induces a physiological effect. Understanding the role of the substance is crucial in various scientific fields for effective applications and outcomes.
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 that speeds up a chemical reaction without permanently being changed itself?
A catalyst is a substance that speeds up a chemical reaction by lowering the activation energy needed for the reaction to occur, without being consumed or permanently altered in the process.
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.
Is catalyst a compound?
No, a catalyst is not a compound itself. A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It remains unchanged chemically at the end of the reaction.
What is a catayst?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the reaction itself. Catalysts work by providing an alternative reaction pathway with lower activation energy, making it easier for the reaction to proceed.
Define catalyst to a catalyst?
A catalyst is a substance that accelerates or increases the rate of a chemical reaction. In principle a catalyst should remain unaffected during the process. However normally it loses some activity during it resuses.
Do barium and barium have a reaction?
No. A substance will not react with itself.
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 (:
