A substance by itself will not slow down a chemical reaction; factors require change, such as cooling the reactants or lowering the concentration, to do so. Adding another chemical or substance that happens to slow a reaction often does so by actually interfering with the reaction and replacing or preventing it outright, and there is not a name for chemicals that do this -?inhibitor?-, since a chemical may do this to one reaction, but be a catalyst to another.

The substance that slows down a chemical reaction is an inhibitor. Instead you could also call an inhibitor an anticatalyst.-anticatalyst `antee'katlist1. (chemistry) a substance that retards a chemical reaction or diminishes the activity of a catalyst
Usually:decreasing concentrationlowering the temperaturesometimes lowering pressureremoving any catalyst
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.
inhibitor
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.

if at the end of the chemical THAT substance is unchanged .That substance is a catalyst. If it slows donw the reaction, it is called an inhibitor.
An inhibitor is a substance that slows down or stops a chemical reaction by interfering with the reaction process. This can be achieved by binding to the reactants, blocking active sites on enzymes, or changing the pH of the environment to make the reaction less favorable.
Chemical reactions can be either sped up or slowed down by catalysts.

A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy without being consumed in the process. An inhibitor, on the other hand, is a substance that decreases the rate of a chemical reaction by interfering with the reaction steps or blocking a catalyst.
An inhibitor decreases the reaction rate
* 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.
A catalyst is a material that speeds up a chemical reaction by providing an alternative pathway with lower activation energy. Alternatively, an inhibitor is a material that slows down a chemical reaction by blocking the active sites on the reactant molecules, preventing them from coming together or reacting.
