1. Saponification of ethyl acetate with alkali proceeds according to the reaction:
CH3COOC2H5 NaOH —-> CH3COONa C2H5OH
The kinetics of this reaction was studied by titrating samples of the same
volume (10 ml) of 0.01 M HCl solution. The titration results are shown below:
t, min 0 4.9 10.4 28.2 ∞
VHCl, ml 61.95 50.59 42.40 29.35 14.90
Calculate the reaction rate constant.
