Chapter 17: Reaction Rates
Rates
of Reactions This is a Shockwave animation that shows on a particle level how different factors can affect the rate of reaction. In your Science Journal, describe how each factor in this animation increases the rate of reaction.
More about Rates of Reactions Visit this site for more information about reaction rates. This site includes information about catalysts too. Look at the graph of the activation energy required with and without
a catalyst. Has does adding a catalyst affect the activation energy?
Catalysts
and Reaction Rates Visit this site to learn how a catalyst can alter the rate of a chemical reaction. In the ethane reaction on this Web page the catalyst is not used up in the chemical reaction,
but it has to be replenished. Read through this Web site to find out why?
A
Biography of Ahmed Zewail Ahmed Zewail won the Nobel Prize in Chemistry in 1999. This site contains a very interesting biography of this scientist. Read this article to find out many things including
how Egyptian students were selected for universities. Do you prefer the system in the United States or the one in Egypt?
How Self-Healing
Spacecraft Will Work Visit this site to learn about new composite materials that are being developed that mend their own hairline cracks. Read this Web page to find out the role that catalysts are
playing in this process.
How
catalytic converters work Visit this site to learn how a catalytic converter works? Why is it important for the catalyst to have a large surface area?
