  • Is the acid hydrolysis of ethyl acetate a zero order reaction?

    Although it is termolecular (molecularity =3) reaction, its order is 1 as the concentration of H+ ion and H2O remains constant during the reaction.

  • Is acid catalysed hydrolysis of ethyl acetate a pseudo first order reaction?

    Acid catalysed hydrolysis of ethyl acetate follows a pseudo-first order kinetics with respect to ester . If the reaction is carried out with large excess of ester , the order with respect to ester will be. The rate law equation for a reaction A rarr B is , r = k[A]^(0) If
  • The acidic hydrolysis of ethyl acetate is a first order reaction because water is present in excess and does not affect the rate of reaction and acid is present in trace amounts while the alkaline hydrolysis of esters is a second order reaction because in alkaline hydrolysis the amount of NaOH influences the rate of
