It is called an inhibitor.
surface area
Chemical reactions can be either sped up or slowed down by catalysts.
most chemical reactions dealing with enzymes preform best in a certain small temperature range, so increased or decreased temperatures could result in the slowing down of reactions
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
your ugly face
any chemical which slows down nerve transmission in your body. alcohol being a good example!
In biological chemical reactions, examples of these are called enzyme inhibitors. Enzymes speed up reactions, but enzyme inhibitors slow them down. This can be by either competing with the reactants for a spot on the enzyme, or by altering the enzyme's structure so that it does not speed up reactions anymore. In either case, enzyme inhibitors slow down chemical reactions.
The cold drains batteries because it slows down the chemical reactions inside the battery, reducing its ability to generate and store electrical energy efficiently.
The opposite of a catalyst is an inhibitor. An inhibitor slows down or prevents a chemical reaction from occurring by interfering with the reaction process. This can result in a decrease in the rate of the reaction or a complete halt in the reaction.
A single chemical that breaks down into other substances during chemical reactions is "decomposing".
it is broken down to fuel chemical reactions & is created by chemical reactions.
negative catalyst.
