positive catalyst
Substances that speed up the rate of reaction are called catalysts. Catalysts participate in chemical reaction but does not get consumed. Yeast is an example of biological catalyst.
A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does so by providing an alternative reaction pathway that requires less energy to initiate the reaction. The catalyst itself remains unchanged at the end of the reaction and can be used over and over again.
A catalyst is a substance that speeds up the rate of a chemical reaction without changing the substance. It does this by reducing the minimal reaction energy. A catalyst is not used up in a reaction therefore they last indefinitely.
When a catalyst is used in a chemical reaction, the reaction rate typically increases. This is because the catalyst provides an alternative reaction pathway with lower activation energy, allowing the reaction to proceed more quickly. Catalysts themselves are not consumed in the reaction and can be reused.
positive catalyst
* 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.
The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.
Its a inhibitor.Science worksheet? I just finished it! Lol
A catalyst alters the rate of a chemical reaction.
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
A catalyst can speed up a chemical reaction. Another possible answer in the Biological sense is that Enzymes speed up chemical reactions, but these enzymes are catalysts of the chemical reactions.Different catalysts catalyse different reactions. For example iron is used as a catalyst in the Haber process (manufacture of ammonia).

A catalyst is a material that promotes a chemical reaction by its mere presence. It isn't changed or consumed in the process. Wikipedia has more information, and a link is provided.
A catalyst doesn't undergo a chemical change during a chemical reaction.
