	Introduction to Catalysis: http://www.youtube.com/watch?v=__90F8k8X78 Comments: Excellent qualitative discription of catalysis.
	Selectivity and Equilibrium: http://www.youtube.com/watch?v=gLMTBWU76dc Comments: Good qualitative description on why you would use a catalysis.
	Introduction to Adsorption: http://www.youtube.com/watch?v=hreAO6Iqraw Comments:Good explaination. Nomenclature used to derive the Langmuir Isotherm is a little different in that the fraction of vacant sites θV,and fractional coverage of species B θB are used instead of the concentration of vacant sites Cv and the concentration of adsorbed species B Cb. The fraction of vacant sites is just the concentration of vacant sites divided by the total number of sites &theat;V =Cv/Ct and the fractional coverage of B is just Cb/Ct. This concept of fractional coverage is similar to what is used later in the chapter when discussing CVD.
	Langmuir Isotherm : Dissociative Association: http://www.youtube.com/watch?v=fbFkGmHyyE4 Comments: Nomenclature is similar to that used in Adsorption Video discussed above in that it uses fractional coverage.
