For a chemical reaction to occur, the reactants have to meet threshold energy called the activation energy. A catalyst is a substance that speeds up...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our exper...
What happens to the reactants in a chemical reaction? What is a chemical reaction and what are some examples? What is a chemical combination reaction? What is not conserved in a chemical reaction? What does a catalyst do in a chemical reaction?
How does mass change during a chemical reaction? Building Blocks Of Matter: All matter is made up of tiny building blocks called atoms. Atoms are bonded together to form molecules and compounds, which make up everything that exists in the universe. The amount of matter in a substance is dir...
The mixture is actually detecting the presence of such a catalyst, in this case the iron in hemoglobin (see Microsoft Encarta: Catalysis for more information on catalysts). To perform a luminol test, the criminalists simply spray the mixture wherever they think blood might be. If hemoglobin ...

Enzymes are proteins in biological systems that help speed along reactions that would otherwise take place far more slowly than without the aid of the enzyme. As such, they are a kind of catalyst. Other, non-biological catalysts play a role in industry and elsewhere (for example, chemical cat...
•Physical state of reactants:Powders dropped in solution react faster than solid chunks like tablets do because they expose a greater surface area for reactions to occur immediately. •The presence, type and concentration of a catalyst or inhibitor:A catalyst speeds up a reaction, while inhib...
In previous polyesterification reactions, the concentrations of reactants and catalyst (if present) were all expressed in moles per kilogram. In most cases, the progress of reaction was followed by the titration of acid groups. Consequently, the removal of condensation water is bound to affect th...
