You weigh out 300mg of benzoic acid and dissolve it in 3ml of diethyl ether. this is then extracted with 3ml of water. the ether layer is removed, dried with sodium sulfate and the ether evaporated yielding 100mg of benzoic acid. what is the kp value (partition coefficient) for the ether/water system?

2b2t

explanation:

2b2t

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
