The second-order hydrolysis reaction of ethyl acetate, CH3COOC2H5(aq) + H2O(
) CH3COOH(aq) + C2H5OH(aq) ,follows pseudo-first-order reaction kinetics in solutions in which the molarity of water is assumed 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 10-3 M -1 s-1
B) 1.27 10-3 M -1 s-1
C) 3.61 10-5 M -1 s-1
D) 0.111 M -1 s-1
E) 6.67 M -1 s-1
