Welcome to Wikipedia. Everyone is welcome to contribute to the encyclopedia, but when you add content (particularly if you change facts and figures), as you have to the article chemical reaction engineering, please cite a reliable source for the content you're adding or changing. This helps maintain our policy of verifiability. Take a look at Wikipedia:Citing sources for information about how to cite sources and the welcome page to learn more about contributing to this encyclopedia. subst:subst PDCook (talk) 19:42, 3 December 2009 (UTC)
