A Reaction Where a Catalyst Is Used
Answers to Common Questions
Question doesn't make sense, a catalyst is a substance that initiates or accelerates a reaction
Anything that acts that way is a catalyst. It is the definition.
Catalysis involves lowering the activation energy barrier for a given reaction. This in turn speeds up the reaction. Catalysts are defined as any chemical that helps speed up a reaction by catalysis. Therefore, catalysts can never slow down...

Yes, it can be a reactant, and if so, it is also a product. It can get "used", but not "used up". Many chemical reactions take place as a series of steps. A catalyst can be a reactant in one step and a product in a later...

Catalytic cracking has used alumina (aluminum oxide, Al2O3) as the catalyst. It works by lowering the energy required to cleave C-C bonds when the larger hydrocarbon molecules are adsorbed on the surface of the alumina particles. More recen...

No, generally a catalyst is conserved when used in a chemical reaction. This is because the catalyst is not directly involved in the reaction, that is, it does not undergo chemical change.

Catalysts cannot change the free energy of a reaction. They merely accelerate the reaction by lowering the energy of activation.

In most cases a catalyst actually is a reactant. Reactions usually occur in multiple steps. Therefore, the catalyst is a reactant in an early step and a product in a subsequent step. The catalyst speeds up the reaction by providing a new re...

the reactants collide with the catalyst and bind to it, they are bound in a way that aligns them correctly so that a reaction is favored, once the reaction occurs the catalyst realeses them.

It is not used up as it is a substance that the reactants can stick to, so there are more succesful collisions (collision theory), increasing the rate of reaction; as opposed to reacting with the reactants.
