1. The unique flavour of fruits and berries is due to the presence of esters, chemical compounds that are easily synthesized in the lab. For example, ethyl propanoate is responsible for the flavour characteristic to pineapple. It is produced by the reaction: C₂H5OH(1) + C₂H5COOH(1)→ C₂H5COOC₂H5(1) + H₂O(1) When 7.71 mol of C₂H5OH(1) and 7.37 mol of C₂H5COOH(1) are reacted in a beaker, 4.80 mol of C2H3COOC₂H5(1) are present when equilibrium is established and the total volume of liquid is exactly 1.00 L. a) Calculate the Keq for this system. (Value: 4 marks) b) Are the reactants or products favoured at equilibrium? Justify your choice. (Value: 2 marks)
