What should i do, shoul i heat up or cool down my dehydration reaction between a carboxylic acid and p2o5 to form an anhydride?
Accepted Answer
To favor anhydride formation, you should heat the reaction. This is because the dehydration of a carboxylic acid to form an anhydride is an endothermic reaction. Applying heat provides the necessary energy to overcome the activation energy barrier and drive the reaction forward, promoting the formation of the anhydride. Additionally, heating helps to remove the water produced as a byproduct, shifting the equilibrium towards the anhydride product.
