what is the expected outcome of adding a catalyst to a chemical reaction?
531405
In the presence of a catalyst, both the forward and reverse reaction rates will speed up equally, thereby allowing the system to reach equilibrium faster. However, it is very important to keep in mind that the addition of a catalyst has no effect whatsoever on the final equilibrium position of the reaction.

Catalysts are chemical compounds that increase the rate of a reaction by lowering the activation energy required to reach the transition state. Unlike reactants, a catalyst is not consumed as part of the reaction process.

But there is another type of reaction that will also push the reactants to products and that is an Oxidation-Reduction (Redox) reaction which is driven by the irreversible transfer of electrons. I say this reaction is "irreversible" because the spontaneous transfer of electrons only proceeds in one direction.

Chemical equations show us the products of the reactions and how they are formed. They are useful to predict the products of a reaction. Using this rule, we can predict what will if magnesium (a metal), reacts with hydrochloric acid (an acid, of course!).

In some reactions, a single-reactant substrate is broken down into multiple products. In others, two substrates may come together to create one larger molecule. Two reactants might also enter a reaction, both become modified, and leave the reaction as two products. The enzyme's active site binds to the substrate.

A chemical reaction happens when one or more chemicals are changed into one or more other chemicals. Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water.

A chemical change must occur. One example of a chemical reaction is the rusting of a steel garbage can. That rusting happens because the iron (Fe) in the metal combines with oxygen (O2) in the atmosphere. Chemical bonds are created and destroyed to finally make iron oxide (Fe2O3).

A Catalyst is a substance that speeds up a chemical reaction but is not changed itself by the reaction and can be used again. Examples of catalysts include platinium which is used in car exhausts to break down harmful emissions and yeast is a biological catalyst that speeds up the process of fermentation.

Explanation: Synthesis reactions are chemical reactions where two elements combine to make a product. ... Decomposition reactions are chemical reactions where a reactant produces another product, usually two or more. This is when the bonds in the compound are broken apart to form new compounds.

During a chemical reaction no atoms are created or destroyed. The atoms are rearranged. This results in the formation of new substances with different properties to the starting substances.

Lesson Summary. A synthesis reaction occurs when two or more reactants combine to form a single product. In a decomposition reaction, one reactant breaks down into two or more products. This is the reverse of a synthesis reaction.

A chemical change must occur. Chemical bonds are made or broken in order to create a new molecule. One example of a chemical reaction is the rusting of a steel garbage can. That rusting happens because the iron (Fe) in the metal combines with oxygen (O2) in the atmosphere.

Like most chemical reactions, the rate of an enzyme-catalyzed reaction increases as the temperature is raised. A ten degree Centigrade rise in temperature will increase the activity of most enzymes by 50 to 100%. ... Over a period of time, enzymes will be deactivated at even moderate temperatures.

A chemical reaction is usually accompanied by easily observed physical effects, such as the emission of heat and light, the formation of a precipitate, the evolution of gas, or a color change. Absolute confirmation of a chemical change can only be validated by chemical analysis of the products!

One of the Following Does Not Happen During a Chemical Reaction. this Is: (A) Breaking of Old Chemical Bonds and Formation of New Chemical Bonds (B) Formation of New Substances with Entirely Different Properties (C) Atoms of One Element Change into Those of Another Element to Form New Products.

Catalysts are substances that increase or decrease the rate of a chemical reaction but remain unchanged. Enzymes are proteins that increase rate of chemical reactions converting substrate into product. Low molecular weight compounds.

Specific-acid catalysis refers to a process in which the reaction rate depends upon the specific acid and not upon other acids present in the solution. ... The term "general" refers to the fact that any acid or base we add to the solution will affect the rate of the reaction, and hence the catalysis is quite general.
