Hydrolysis is an organic reaction that breaks chemical bond with a molecule of water. The below synthetic route shows the hydrolysis reaction of esters in the presence of acid. HO HSO4 (c) How would the reaction rate change if the reaction is carried out at higher temperature? Explain your answers. (4 marks) (d) Amidation is the organic reaction of a carboxylic acid and an amine to produce amide. (i) H-C-C HO H OH Acetic acid HHH + H-C-C-N-H H H Ethylamine HO H-C-C-N-C-C-H + HO HH H HHH Amide Given that amidation reaction is endothermic, how would the equilibrium position change if the reaction is carried out at lower temperature? Explain your answers. (3 marks) (ii) Assume esterification reaction occurs in a solution. Given that the K. value of the above reaction at certain temperature is 5.2. If a reaction mixture contains 0.13 M acetic acid, 0.64 M ethylamine and 0.78 M amide at a certain reaction timepoint, to which direction would the reaction proceed? Show your calculations.
