Q:

What is the term for a substance that slows down a chemical reaction?

A:

Quick Answer

A substance that slows or prevents a chemical reaction is called an inhibitor or a negative catalyst. It is the opposite of a catalyst, which is a substance that increases the rate of a reaction.

Full Answer

An example of an inhibitor is acetanilide. When it is added to hydrogen peroxide, it slows down the decomposition of the solution. Inhibitors are also used alongside catalysts, such as enzymes, to reduce their effectiveness. Poisons and some drugs can act as enzyme inhibitors. Enzyme inhibitors can be classified as specific or nonspecific. A specific inhibitor works on a single type of enzyme, and a nonspecific inhibitor has the same effect on all enzymes.

    What happens to matter during a chemical reaction

    A:

    During a chemical reaction, matter undergoes a change in chemical substance. Different types of chemical reactions include synthesis reactions, substitution reactions, chemical decomposition, acid-base reactions, double displacement reactions, redox reactions, combustion, isomerization and hydrolysis. Chemical reactions generally involve electron displacement, however, nuclear chemical reactions also involve changes in atoms' nuclei.

  • Q:

    What happens during a chemical reaction?

    A:

    The molecules of one reactant are combined with those of another reactant to form a new substance during a chemical reaction. As the chemical bonds are broken, the positions of electrons change, resulting in a product with properties that are different from the properties of the reactants. Various temperatures and catalysts are needed for different chemical reactions to occur.

    What are some signs to look for when determining if a chemical reaction has taken place?

    A:

    There are a few telltale signs that can help indicate that a chemical reaction has taken place; these include the creation of one or more new substances and a noticeable energy change from the reaction site. However, telling whether a chemical reaction has actually taken place is not always very easy to observe.

  • Q:

    How is burning a match a chemical reaction?

    A:

    Burning a match is a chemical reaction because the reactant, primarily wood, is chemically altered into a different substance, ash. A chemical reaction or change involves one or more reactants having bonds broken or altered to form new substances. In the case of burning a match, wood and oxygen are transformed into ash and smoke, two distinctly new products.
