  2. Esterification CH3COOH+CH3CH2OHCH3COOCH2CH3+ H2O Assumption: • Very slow equilibrium • Acid-catalysed • Constant temperature • Closed system

  3. Calculation For Expt I: Volume Of NaOH used = V1 dm3 For Expt A: Volume Of NaOH used = V2 dm3 Concentration at equilibrium CH3COOH+CH3CH2OHCH3COOCH2CH3+ H2O where V= V2 V1 ;M = [NaOH]; d = density of the ester
