Questiоn 8 This questiоn is аbоut esters. Ester A reаcts with wаter to form ethanoic acid and ethanol. The displayed formulae of the reactants and products are shown in this equation The molar enthalpy change (ΔH) for the reaction is 0 kJ/mol. ai Draw a ring around the functional group in ester A. (1) aii Give the name of ester A. (1) aiii Describe a chemical test, other than using an indicator, to show that the reaction mixture contains ethanoic acid. (2) b Explain why the molar enthalpy change (ΔH) for the reaction between ester A and water is 0 kJ/mol. (2) In your answer, refer to the bonds broken and the bonds formed. c A mixture of ester A and water is left in a sealed container until the reaction mixture reaches dynamic equilibrium. ci Describe what is meant by dynamic equilibrium. (2) cii Explain why adding a catalyst does not change the position of equilibrium. (2) d The ethanoic acid produced in the reaction is completely neutralised by 22.75 cm3 of 0.150 mol/dm3 barium hydroxide solution. (3) The equation for the neutralisation reaction is 2CH3COOH + Ba(OH)2 → Ba(CH3COO)2 + 2H2O Calculate the amount, in moles, of ethanoic acid neutralised. Give your answer to 3 significant figures. e The structures of two organic compounds are shown. (2) These compounds react together to form a polymer. Give the repeat unit of the polymer formed.
