The second-order hydrolysis reaction of ethyl acetate. CH_3COOC_2H_5(aq) + H_2O(l) rightarrow CH_3COOH(aq) + C_2H_5(aq), follows pseudo-first-order reaction kinetics in solutions in which the molarity of water is assumed to be roughly constant at 55.5 M. An experiment using an initial CH3COOC2H5 concentration of 0.06500 M is conducted under pseudo-first-order conditions. After 60 seconds, [CH3COOC2H5] = 0.05764 M. Estimate the second-order rate constant.
a. 2.00 times 10^-3 M^-1 s^-1
b. 1.27 times 10^-1 s^-1
c. 3.61 times 10^-5 M^-1 s^-1
d. 0.111 M^-1 s^-1
e. 6.67 M^-1 s^-1
