One of the things I learned in this unit is the importance of understanding the different types of reactions that can occur in a chemical reactor, such as exothermic and endothermic reactions. I also learned about the different factors that can affect the rate of a chemical reaction, such as...
Impact of reaction products from building materials and furnishings on indoor air quality—A review of recent advances in indoor chemistry and furnishings provides potential for chemical reactions in the material (case 1), on the material surface (case 2) and in the gas phase (case 3)... E ...
I. Evidence of electrophilic attack by hydrated monomeric and dimeric copper(II) species The rate of mutarotation of α-D(+)-glucose is markedly affected bythe addition of electrolytes. At 293 K the rate constants for reaction with H2 CJ,O'Conner,AL,... - 《Australian Journal of Chemistry...
The chemical engineer must work closely with the chemist in order to understand thoroughly the chemistry involved in the process and to make sure that the chemist gets the reaction kinetic data and the physical property data needed to design, operate, and optimize the process. This is why the ...
