But then thermo was never my strong point. Pete Gannett >>> Qiang Lu 7/16/2004 4:11:17 PM >>> Hi CCLERs, Think about the following two reaction: A + B-H = AB-H A + B = AB The total energy of AB-H is lower than AB, but the binding energy between A and B of AB is higher than that of AB-H. Then which state is prefer between AB-H and AB? In another words, is it prefer a deprotonated state of AB-H or not in the nature? -- Best regards, Qiang Lu mailto:qiangl{at}uci.edu -= This is automatically added to each message by the mailing script =- To send e-mail to subscribers of CCL put the string CCL: on your Subject: line and send your message to: CHEMISTRY{at}ccl.net Send your subscription/unsubscription requests to: CHEMISTRY-REQUEST{at}ccl.net HOME Page: http://www.ccl.net | Jobs Page: http://www.ccl.net/jobs If your mail is bouncing from CCL.NET domain send it to the maintainer: Jan Labanowski, jlabanow{at}nd.edu (read about it on CCL Home Page) -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
