esterification
« on: July 14, 2005, 04:27:20 AM »
esterification of acetic acid with ethanol is an exothermic reaction, so according to le chatlliers principle the conversions should decrease with increasing temperature but some literature shows that conversion actually increase with increasing temperature.
can anyone tell me the reason behind increased converions.i am attaching a paper that says that conversion increases with temperature.

Perhaps It's kinetics versus thermodynamics. Heat speeds up the conversion process (getting over the activation energy barrier). Thermodynamically, You can theoretically get greater converion letting sit without heat, but how long are you willing to wait?

Like combustion is exothermic but will occur more rapidly with heat.

(I couldn't see the article due to pc download problem.)
