Palmitic acid is one of fatty acids found in butter. It is a saturated fatty acid containing 16 carbon atoms. A student performed the reaction between palmitic acid and methanol in the presence of acid catalyst to give the corresponding ester. 1. Draw the reaction occurred in this experiment! 2. Given that enthalpy of formation palmitic acid, methyl palmitate, methanol and water are -764, -726, -238, -285 KJ/mol, respectively. Determine the enthalpy of the reaction! 3. Methyl palmitate can be utilized as a starting material in the production of soap through saponification reaction. Draw the reaction occurred in this process!
