Question
II.2- Saponification of ethyl ethanoate, a second-order kinetic?
Data: R = 8.314 J mol·' K-'
The kinetic study of the saponification reaction of ethyl ethanoate by caustic soda (sodium hydroxide
NaOH):
CH3COOCH2CH3 + OH → CH3CO2¯ + CH3CH2OH
was achieved at 298 K for initial concentrations a in ester and hydroxide that are identical.
Experimental results, for different values of a, are reported in the following table:
a (mol L-')
0.1
7.5 × 10-2
5 x 10-2
4 x 10-2
t1/2 (s)
6.66 x105
8.89 ×10$
1.33 ×106
1.66 ×106
Recall the differential expression of the rate law for a second-order kinetic, with a partial order
of 1 to each of the individual reactants. When initial concentration of each of the reactant is
the same, deduce the expression of the integrated form of this equation. The rate constant will
be denoted k and the concentration of each of the compounds produced (products) will be
called x.
