  • What is the activation energy of ethyl acetate saponification?

    Activation energy: 41.4 ± 0.6 kJ mol?1.

  • What is the activation energy of saponification of ethyl acetate and NaOH?

    ?E?=10. 207Kcal/mole.

  • What is the kinetics of hydrolysis of ethyl acetate?

    The kinetic study of hydrolysis of ethyl acetate is catalysed by an acid, and is followed by titrating a fixed volume of a reaction mixture with a standard alkali solution, at different intervals of time. The ester hydrolysis is acid catalysed.
  • Also, that the rate constant for the hydrolysis of ethyl acetate with sodium hydroxide using HCl as a catalyst at 28oC is approximately 0.003min-1cm-3.
